[00:00:10.640]Hello again, and thank you
[00:00:12.230]for continuing with us on our exciting journey
[00:00:14.650]as we learn more about embryology
[00:00:16.710]through the Nebraska 4-H "Embryology 101" Program.
[00:00:20.820]This is the fourth and final lesson
[00:00:23.260]that will guide you through the development of embryos
[00:00:25.950]in chicken eggs.
[00:00:28.950]As I said in our previous videos
[00:00:30.690]my name is Sarah Paisley and I am the Extension Educator
[00:00:33.750]for Garden and Morrill Counties.
[00:00:35.620]I am excited to be your co-host again
[00:00:37.410]as you continue this virtual journey
[00:00:39.200]of embryo development.
[00:00:41.010]Today I will be joined by Beth Janning
[00:00:43.670]of Adams and Webster counties.
[00:00:45.830]Today Beth is going to take us on an exciting journey
[00:00:49.290]from the chicken house to your table.
[00:00:53.140]Before we get started on our journey though
[00:00:55.530]I need you to get out your questions page
[00:00:57.960]from the last time we met.
[00:01:00.360]Remember the one I told you to keep it in a safe place?
[00:01:03.170]At the end of the lesson
[00:01:04.430]I asked you to add any questions that you still had
[00:01:07.040]and to answer the ones we may have answered
[00:01:09.660]during the lesson.
[00:01:11.060]Do you still have a lot of questions?
[00:01:13.810]Take a moment to reread them.
[00:01:15.930]Pause the video if you need to.
[00:01:18.810]Does looking at these questions
[00:01:20.340]spark up any other ideas?
[00:01:22.950]Write it down if it did.
[00:01:25.860]We are going to look at one last picture
[00:01:27.970]and this picture today is from Ag in the Classroom
[00:01:30.710]which is a program sponsored by Farm Bureau.
[00:01:33.230]You will do the same thing that we have done in the past
[00:01:35.510]write down any questions that pop into your head.
[00:01:38.070]Are you ready to write any questions that you have
[00:01:39.830]about this picture?
[00:01:41.280]Okay, here we go.
[00:02:16.680]Thanks for thinking about this picture today.
[00:02:19.130]Don't put this paper away this time
[00:02:21.060]as Beth will have you using it again right away.
[00:02:25.050]Before she gets started though
[00:02:26.340]I have one last thing I wanted to do with you.
[00:02:29.080]As we look at our chart from Alabama Cooperative Extension
[00:02:33.180]to check on how our embryo has been changing.
[00:02:36.490]we have reached our 18-day mark
[00:02:38.240]so if you remember,
[00:02:40.040]Melissa told us some really important things
[00:02:42.340]we needed to do.
[00:02:43.720]The incubator bottom has as much water as it can hold,
[00:02:46.710]the plug has been removed, and we do not open the incubator.
[00:02:50.320]The embryos have gone through a ton of transformations
[00:02:54.240]as they have gone through this 21-day process.
[00:02:57.800]What we're gonna see here the next couple of days
[00:03:00.213]is that the embryos will peck a hole in the air cell
[00:03:04.550]and they will begin to breathe.
[00:03:06.320]They will also start pipping which is them cheeping
[00:03:10.640]from inside the egg and then they start
[00:03:13.210]to peck holes in the shell.
[00:03:14.990]And this can be a very long and exhausting process,
[00:03:18.090]but it's amazing to see them finally get out of their shell.
[00:03:23.190]Okay, it is about time to start our lesson
[00:03:25.170]but I want you to see our objectives
[00:03:26.520]for this fourth lesson called, "The Traveling Egg."
[00:03:29.320]By the end of the day you will be able
[00:03:30.780]to recognize the benefits and drawbacks
[00:03:33.030]between housing options
[00:03:35.050]and understand where chicken meat and eggs come from.
[00:03:37.890]So without further ado, let's turn this over to Beth.
[00:03:42.140]Hi, I am Beth Janning,
[00:03:43.660]and I am 4-H Youth Development Extension Educator
[00:03:47.040]for Nebraska Extension.
[00:03:48.800]I'm excited to be here with you
[00:03:50.230]and I am glad that you have joined us
[00:03:52.060]with our embryology series.
[00:03:54.440]And this session is about "The Traveling Egg,"
[00:03:56.997]and we're gonna discuss how the egg
[00:03:59.410]gets from the farm to the table.
[00:04:01.890]So we're gonna go ahead and get started
[00:04:03.940]and so as you created your list
[00:04:06.960]I hope that there were a few things that you noticed
[00:04:09.750]about these cartons.
[00:04:11.360]One of them is that you might notice
[00:04:13.550]that there are different words on them, okay.
[00:04:18.440]So you may notice that all of 'em say
[00:04:21.020]that there's large, you may also notice
[00:04:24.920]that they have different words such as cage-free,
[00:04:29.360]free-range, and do you think there is a difference
[00:04:34.240]in these eggs if you open them up,
[00:04:36.350]if you open those cartons up,
[00:04:37.830]do you think that there would be any difference?
[00:04:41.820]For those of you that said, "No,"
[00:04:43.250]you are correct because they're all large size,
[00:04:47.340]they would all be about the same size,
[00:04:49.440]they're all the same shape
[00:04:52.600]and when we think about this
[00:04:54.830]do you think there's any difference
[00:04:56.490]in nutritional value?
[00:04:59.870]For those of you that said, "No"
[00:05:01.320]you guys are correct.
[00:05:02.720]Even though these are different
[00:05:04.900]there's no difference in nutritional value
[00:05:08.450]they all have about the same amount of protein
[00:05:11.390]as a part of that.
[00:05:12.223]So my other question to you is what makes them different?
[00:05:16.700]Did you have a question about what made them different?
[00:05:23.300]If it's a part of what you guys thought about,
[00:05:25.540]of the words free-range, cage-free,
[00:05:27.980]and the other one not having that,
[00:05:30.650]it is all based upon the housing
[00:05:32.800]of how those animals are cared for.
[00:05:35.530]And so it's something to think about
[00:05:37.190]that there's no nutritional value difference,
[00:05:39.590]there's no difference in that nutrition,
[00:05:41.710]but the way that those animals,
[00:05:44.850]or those chickens are housed.
[00:05:47.300]So I want us to come up with some questions
[00:05:49.990]and I want you to brainstorm when you think about it
[00:05:53.370]of what do you think those differences are between those?
[00:05:57.560]Do you have any guesses?
[00:05:59.120]Go ahead and write those guesses down.
[00:06:04.240]Some of you may have talked a little bit
[00:06:06.490]about wanting to know what that hen housing looked like.
[00:06:08.980]So what do those female chickens,
[00:06:11.580]that are laying those eggs,
[00:06:12.780]what does the housing system look like,
[00:06:14.930]or their chicken houses.
[00:06:16.900]You may ask is one best for the hens compared to others?
[00:06:21.700]You may ask is one better for the farmers
[00:06:24.680]that are raising these chickens,
[00:06:26.150]or better for the consumers?
[00:06:27.900]We are going to watch videos on all four of them
[00:06:31.410]and you are going to help make that decision
[00:06:33.370]of what do you think is the best.
[00:06:37.050]And so with that if you have this Venn Diagram
[00:06:40.300]printed out in front of you,
[00:06:42.220]I want you to go grab that out
[00:06:43.700]so that you can write down what the benefits are,
[00:06:46.630]and what the drawbacks are.
[00:06:47.877]And a benefit are the good things about the housing,
[00:06:50.780]and a drawback is maybe not one of those best parts
[00:06:54.800]for that housing, that housing situation.
[00:06:58.090]And so we're going to watch four of these videos.
[00:07:01.890]If you do not have this Venn Diagram in front of you
[00:07:04.420]just grab a scratch sheet of paper.
[00:07:06.660]You can make something similar
[00:07:08.390]to what is on your screen
[00:07:10.080]and being able to write down those benefits and drawbacks
[00:07:14.040]for each one of those.
[00:07:15.530]We're gonna start off by watching a video
[00:07:19.070]for why chickens are raised in cages, okay?
[00:07:23.410]So this is a video from Raising Nebraska
[00:07:26.360]which Raising Nebraska is a vocational facility
[00:07:29.670]within the Nebraska building, in Grand Island,
[00:07:31.930]on Fonner Park or the state fairgrounds.
[00:07:34.980]Let's take a watch.
[00:07:37.440]All our chickens are in cages.
[00:07:40.260]We feel that's the best way to produce eggs.
[00:07:44.090]It keeps them in a safe environment
[00:07:46.020]where they don't have to worry about any kind of predator.
[00:07:49.430]They have feed
[00:07:50.280]and water access (chickens cheeping)
[00:07:51.800]all the time.
[00:07:53.390]It's clean feed, clean water.
[00:07:55.730]They have air, they're ventilated, there's fans,
[00:07:58.080]there's numerous fans in every barn
[00:08:00.290]that keep fresh air flowing through.
[00:08:02.820]When they get laid in a cage, the eggs are clean,
[00:08:07.010]they're not dirty.
[00:08:08.190]They're not on the dirt, or on the ground.
[00:08:11.850]Over the years cage size,
[00:08:13.350]cage size hasn't really changed that much,
[00:08:16.530]but it's how many birds we put in the cages
[00:08:19.730]so that there's more space for each bird.
[00:08:22.870]We have 812,000 birds.
[00:08:25.860]A chicken lays an egg every 26 hours
[00:08:29.260]and so we produce about 58,000 dozen eggs every day.
[00:08:33.760]The unique thing about chickens is,
[00:08:35.640]is whatever you put in their feed will end up in their eggs.
[00:08:40.300]So kinda whatever they eat that directly correlates
[00:08:44.020]to what's in that egg product.
[00:08:46.070]So you may wanna make sure they got good quality feed
[00:08:49.140]and clean water because whatever's in that feed
[00:08:52.750]will end up, eventually end up in the egg.
[00:08:55.980]So they're constantly looking at new ways,
[00:08:57.920]and new cage designs, and new ways of housing them.
[00:09:03.387]and they're looking at those things all the time
[00:09:05.350]as to how to, you know, make those things better
[00:09:10.504]and it's all for egg quality and welfare of the birds.
[00:09:22.240]So at this time what I want you to do
[00:09:26.510]is to make sure that you write down
[00:09:29.140]the benefits and the drawbacks.
[00:09:31.490]If you need to hit pause, hit pause at any time,
[00:09:34.390]and please make sure that you've written down
[00:09:36.500]the benefits and the drawbacks
[00:09:38.320]under the, why chickens are raised in cages.
[00:09:41.100]If you have that complete
[00:09:42.410]what we're gonna do next is we're gonna watch
[00:09:44.770]a video about cage-free, or what some call free run.
[00:09:49.410]So once again, find that on the diagram sheet
[00:09:53.280]and I want you guys to put the benefits and the drawbacks.
[00:09:57.305](upbeat music)
[00:10:07.260]At Burnbrae we know that consumers
[00:10:10.040]would like to have choice
[00:10:11.490]in the products that they buy.
[00:10:13.640]In 1996 recognizing that consumers want choice
[00:10:17.670]we built our first free-run barn,
[00:10:21.020]also known as cage-free.
[00:10:24.260]They are allowed to move between the levels,
[00:10:27.700]either by flying, or walking up and down ladders
[00:10:31.290]which we provide for them.
[00:10:33.070]And on each level, except for the very bottom level,
[00:10:37.160]which is the floor of the barn,
[00:10:38.830]there is food and water,
[00:10:40.990]and there are nests on the side
[00:10:43.330]where the birds can go to lay their eggs.
[00:10:46.740]They like to lay their eggs in a secluded area,
[00:10:50.030]which can be private,
[00:10:51.680]or they share it with their nest mates.
[00:10:55.110]There's a scratch area on the floor
[00:10:57.390]which allows for complete dust bathing activity,
[00:11:01.210]social pecking, and foraging.
[00:11:04.750]There are benefits, and there are trade-offs.
[00:11:08.300]In the free-run system we can have more problems
[00:11:12.140]with feather pecking and aggression.
[00:11:14.800]We can have problems with piling of hens
[00:11:17.810]if they get scared of something
[00:11:20.000]they pile on top of one another
[00:11:21.790]and they can smother each other.
[00:11:24.000]These systems have a much higher carbon footprint
[00:11:27.560]than your enriched cage housing system,
[00:11:30.910]or your conventional cage,
[00:11:32.780]and it costs a lot more to produce those eggs
[00:11:36.420]because the birds are housed at a smaller density
[00:11:39.890]and they require much more management
[00:11:42.150]and we have more issues with them.
[00:11:44.870]At Burnbrae we're committed to providing choice
[00:11:47.840]because we know that consumers want choice
[00:11:50.300]in their egg products that they purchase.
[00:11:53.780]At Burnbrae Farms the good quality care of our hens
[00:11:57.520]is the number one priority
[00:11:59.570]and housing and animal care go together.
[00:12:18.810]Make sure that you go through
[00:12:19.867]and you have written down
[00:12:21.290]those benefits and those drawbacks.
[00:12:25.600]Press pause if you need to.
[00:12:28.090]All right, we're gonna continue on and do free-range.
[00:12:33.300]Once again, keep track of those benefits
[00:12:35.210]and those drawbacks.
[00:12:37.070]My name's Helen Ann Hudson
[00:12:38.660]and I'm a fourth generation egg farmer
[00:12:42.410]on our family farm in Lyn, Ontario.
[00:12:45.980]Today, we're out at one of our farms in Quebec.
[00:12:49.490]Eggs produced on this farm are free-range, organic.
[00:12:53.860]We are proud to provide eggs from organic free-range farms
[00:12:57.610]for consumers who would like to purchase
[00:12:59.670]those kinds of eggs.
[00:13:00.930]We are proud to provide choice to the consumers
[00:13:03.660]who buy our egg products.
[00:13:06.220]The benefits to birds,
[00:13:07.585]in the free-range system of housing,
[00:13:10.490]are basically related to the natural behaviors
[00:13:13.800]that they're allowed to exhibit.
[00:13:15.710]They have more freedom of movement within the system,
[00:13:18.640]they can lay their egg in a nest,
[00:13:20.690]they can dust bathe, they can perch,
[00:13:23.480]but the added benefit is that they can go outside to forage.
[00:13:28.640]Even though they're allowed access to the outdoors
[00:13:31.300]only a very small percentage of these birds
[00:13:33.660]actually range outside during the time
[00:13:36.590]they're allowed to be out.
[00:13:38.570]Most of them prefer the security of the barn,
[00:13:41.140]and most of them do not stray very far from the barn
[00:13:44.550]where they feel secure.
[00:13:47.320]The disadvantages to a free-range system
[00:13:50.070]mainly center around the increased exposure to disease
[00:13:53.920]because they're outside,
[00:13:55.370]and also the increased potential for predation.
[00:13:59.900]At the end of the day, the cost of a free-range egg,
[00:14:03.030]or an organic egg, is probably the greatest cost
[00:14:06.800]of any type of egg that you can produce.
[00:14:10.360]The hens in this system,
[00:14:11.750]just like any of our other barns,
[00:14:13.480]have access- (chickens murmuring)
[00:14:14.410]To feed and water whenever they would like it.
[00:14:17.500]When the hens are outside
[00:14:19.030]they're just grazing casually, or foraging on the grass,
[00:14:22.890]but their actual dietary requirements
[00:14:25.740]are being met by the feed circulating inside the barn.
[00:14:29.470]Organic feeds never contain medications.
[00:14:32.530]The feed that these birds are fed is non-GMO,
[00:14:36.560]and it's grown free of herbicides and pesticides,
[00:14:40.270]so it's a very specific type of feed
[00:14:43.430]and it's very costly to produce.
[00:14:47.280]At Burnbrae taking good care of our hens
[00:14:49.930]is the number one priority.
[00:14:52.270]When we take good care of them
[00:14:53.930]they produce nutritious wholesome eggs for our consumers.
[00:15:15.080]All right, so hopefully you've written down,
[00:15:17.760]once again, those drawbacks and those benefits
[00:15:21.930]that go under our free-range chickens housing.
[00:15:26.370]Our fourth, and last one,
[00:15:28.530]that we are going to watch is enriched colony housing.
[00:15:32.500]So we're gonna go ahead
[00:15:33.480]and we're gonna watch this video.
[00:15:34.990]Make sure you're writing down those benefits
[00:15:36.780]and those drawbacks.
[00:15:40.900]My name's Helen Ann Hudson
[00:15:42.560]and I'm a fourth generation egg farmer.
[00:15:45.650]I love animals in general,
[00:15:47.590]as anyone who's around here knows.
[00:15:50.350]I've always enjoyed working with chickens.
[00:15:52.730]There are several types of housing systems
[00:15:55.040]for laying hens in our industry.
[00:15:57.200]Within the industry and within those housing systems,
[00:16:01.220]the quality of care for the hens is a top priority
[00:16:05.030]for the farmers.
[00:16:07.090]When Burnbrae farms first started
[00:16:11.080]acquiring laying hens and selling eggs,
[00:16:14.020]they lived out on the range
[00:16:15.210]where they were exposed to more diseases,
[00:16:18.320]predation, and weather extremes.
[00:16:21.500]We also would have to worry about
[00:16:23.350]the birds being aggressive with each other.
[00:16:26.290]And then over the years
[00:16:27.720]we started to build indoor housing for them.
[00:16:30.390]Burnbrae moved towards the conventional cage housing,
[00:16:35.120]where the birds lived in smaller cages.
[00:16:37.310]Those cages were designed to keep them in smaller groups
[00:16:41.110]to reduce the aggression.
[00:16:43.500]Poultry are very aggressive.
[00:16:45.720]There's a new system called the enriched colony cage.
[00:16:49.720]Enriched colony housing offers many benefits to the birds.
[00:16:54.290]It's a compromise between the conventional cage system,
[00:16:59.070]which is being phased out,
[00:17:00.560]and the loose housing, which we call free run or cage-free.
[00:17:05.410]It allows the birds to exhibit natural behaviors,
[00:17:08.720]but still provide you with the benefits
[00:17:11.640]of the cage housing system in that the birds
[00:17:15.110]are easier to manage.
[00:17:17.470]They have the advantage
[00:17:18.690]of having a nesting area in the cage
[00:17:21.470]and they have perches
[00:17:23.070]so that they can get up and roost at night
[00:17:25.840]which is instinctive for them.
[00:17:28.230]Within all of our systems we provide continuous access
[00:17:32.300]to feed and water.
[00:17:34.340]There's less aggression, the eggs are cleaner,
[00:17:37.350]and it's just an environment that's better
[00:17:39.790]for the farm workers.
[00:17:41.650]There's less dust and ammonia.
[00:17:43.910]It's easier to control,
[00:17:45.600]the environmental condition's better,
[00:17:48.100]and it still provides an affordable product.
[00:17:52.000]Today consumers like choice in their products.
[00:17:55.490]The enriched colony hen produces an egg
[00:17:58.530]that we market as the Nestlaid brand.
[00:18:02.290]At Burnbrae Farms the good quality care of our hens
[00:18:06.030]is the number one priority,
[00:18:08.040]and housing and animal care go together.
[00:18:28.550]All right, so I want you guys to think about,
[00:18:31.430]with that Venn Diagram,
[00:18:32.950]and as we think about things,
[00:18:34.580]there is a part of that middle,
[00:18:36.290]and we think about that middle,
[00:18:37.710]there were pieces that were the same
[00:18:40.060]across all four houses.
[00:18:44.480]Did you notice any of that?
[00:18:46.090]So I want you to take a little bit of time,
[00:18:47.680]hit pause if you need to,
[00:18:49.280]go back and watch if you need to,
[00:18:51.970]but at this time I want you to have
[00:18:55.170]benefits and drawbacks for all four,
[00:18:57.930]and what did you notice that was the same across all four?
[00:19:01.930]What were, what was the same regardless of type of housing?
[00:19:05.920]So go ahead and take a moment and do that.
[00:19:07.730]And you may hit pause and when you're ready
[00:19:10.060]you can hit continue.
[00:19:12.100]All right, hopefully you figured out,
[00:19:15.440]or you recognized that food and water was available
[00:19:19.390]in all of those housing.
[00:19:21.080]That care of the chickens was top priority
[00:19:24.070]and a major concern for those farmers
[00:19:26.970]and everyone involved in the care of the animals.
[00:19:29.620]And they also all provided shelter.
[00:19:31.550]So those three pieces are very, very critical
[00:19:35.250]in raising our animals.
[00:19:37.100]And so at this time what I want you to do,
[00:19:39.630]on the back of where you had your Venn Diagram,
[00:19:42.600]I want you to think about if you had your own chickens
[00:19:46.300]which system would you want to house them in and why?
[00:19:49.330]And I want you to really justify
[00:19:51.550]which housing you choose, based upon
[00:19:54.230]those benefits and drawbacks that you recorded,
[00:19:57.300]and be able to think about and back up your reasoning,
[00:20:01.440]that why of which system
[00:20:03.810]you would wanna raise your own chickens in.
[00:20:06.060]So go ahead, press pause,
[00:20:08.250]and write up a description of,
[00:20:10.950]if you had your own chickens
[00:20:12.480]which system would you want to house them in and why?
[00:20:16.450]Alrighty, I hope that you are able to share this
[00:20:21.830]with somebody, whether or not your teacher asks for it,
[00:20:26.120]or someone in your house.
[00:20:28.120]The other part about this lesson
[00:20:30.200]was that we wanted you guys to be able to see
[00:20:32.840]what did your classmates want?
[00:20:34.730]And so you can create a graph,
[00:20:37.900]and I'm just giving you the very basics of this graph,
[00:20:41.850]of where you could put the types
[00:20:43.890]of chicken houses in the bottom.
[00:20:45.580]You do need to write in what those four types of houses
[00:20:49.570]and then the number of students that wanted each housing.
[00:20:53.160]So maybe you need to work with your teacher,
[00:20:56.220]work with your classmates,
[00:20:57.310]to find out what does your graph look like for your class?
[00:21:01.440]The next piece that I want us to think about,
[00:21:04.013]and you are able to see it in some of those pictures,
[00:21:06.730]but how does that egg get from the farm to the table?
[00:21:10.660]So we are going to watch another video.
[00:21:13.350]And this is from Raising Nebraska,
[00:21:15.610]which we've talked about already,
[00:21:17.580]and they are going to start in the grocery store
[00:21:20.620]because we know that we're able to purchase the eggs
[00:21:23.010]in the grocery store.
[00:21:24.300]So this video is gonna start there,
[00:21:26.660]play it backwards to the farm,
[00:21:28.400]and then play it forward again.
[00:21:29.960]So let's take a peek.
[00:21:31.891](upbeat music)
[00:22:53.450]Originally this was to be a puzzle
[00:22:55.660]and if your teacher gave you a puzzle
[00:22:57.250]go ahead and put those together.
[00:22:59.320]If you do not have that in front of you
[00:23:01.250]I want us to take a peek at this slide
[00:23:04.000]and you will see parts are numbered, one through seven.
[00:23:07.630]I want you to think about the video that you just saw
[00:23:10.680]and what words would you put in each of those.
[00:23:13.300]So, think about where, when you,
[00:23:15.930]that process from the farm to the egg,
[00:23:19.090]there's seven main pieces of that process
[00:23:22.640]to be able to make it complete.
[00:23:25.010]So go ahead and write down what you think is number one,
[00:23:29.080]number two,
[00:23:33.120]number three,
[00:23:37.200]four,
[00:23:40.980]five,
[00:23:44.990]six,
[00:23:49.257]and seven.
[00:23:52.980]Press pause if you need to.
[00:23:55.790]All right, so I'm gonna show you those answers
[00:23:58.720]and so when we think about that process,
[00:24:00.800]or that model from Farm to Table,
[00:24:03.090]we start off with laying the egg.
[00:24:04.990]And as you learned today
[00:24:05.880]there's four different types of housing
[00:24:08.130]that are available for that chicken to lay the egg in.
[00:24:11.150]And so we can't do anything of this
[00:24:13.090]without the laying of the egg.
[00:24:15.440]From the laying of the egg
[00:24:16.670]it moves through the barns
[00:24:17.990]and then you have to sort the egg
[00:24:20.050]based upon size, and cleaning of that,
[00:24:24.410]size and quality of that egg.
[00:24:26.240]Then you have to package the egg.
[00:24:30.290]Number four is transporting it.
[00:24:32.050]And so it needs to go from where it was laid,
[00:24:36.120]and packaged, to the grocery store.
[00:24:39.250]And so it goes through transportation,
[00:24:41.370]it has to be unloaded off of the truck,
[00:24:44.580]and then we need the grocery store
[00:24:47.200]to stock it on the shelves,
[00:24:48.950]and then the consumer, which is you,
[00:24:50.900]to be able to buy it.
[00:24:52.890]Think about the process and this really simplifies it
[00:24:56.720]into seven steps as a part of that.
[00:24:58.860]So we have to lay the egg, we need the sort the egg,
[00:25:01.900]so that it based upon size and quality,
[00:25:04.630]then you package it.
[00:25:05.950]We have to transport it from farm to the grocery store.
[00:25:09.550]You unload it, someone has to put it on the shelves
[00:25:12.610]at the grocery store
[00:25:13.510]and then you are able to buy it.
[00:25:17.000]So when we think about today
[00:25:19.030]I want us to reflect a little bit.
[00:25:20.640]Was there something that just really surprised you the most?
[00:25:28.080]I want you to also share with someone
[00:25:30.410]the answer to if you had your own chickens
[00:25:32.430]which housing would you want and why?
[00:25:35.480]The next thing that I want us to do
[00:25:37.000]is I want you to share with your family, or your friends,
[00:25:39.600]something that you learned today.
[00:25:40.940]So think about what we discussed
[00:25:42.940]and be able to go back and share it
[00:25:44.510]with your family, or your friends.
[00:25:47.350]The other thing is when we think about
[00:25:49.070]that Farm to Table model,
[00:25:51.060]is this similar to other protein animals?
[00:25:53.670]So when we think about our other protein animals,
[00:25:56.070]that would be our beef cattle,
[00:25:58.130]to be able to give us our meat,
[00:26:01.240]is it the same with our pigs that we're able to get pork,
[00:26:04.830]and do you think it's the same with our sheep
[00:26:06.500]where we're able to get lamb?
[00:26:09.320]So do you think that Farm to Table model is the same,
[00:26:12.600]or similar, for other protein animals?
[00:26:15.880]My last question for you,
[00:26:17.180]how would you learn if you wanted to learn
[00:26:18.900]a little bit more about it?
[00:26:23.340]I wanna say thank you for joining us today
[00:26:25.350]and we want to hear from you.
[00:26:27.090]If you are willing to post your story,
[00:26:29.900]or be able to show what you did,
[00:26:32.710]please put it up on social media,
[00:26:35.380]using the #NE4HEGGS.
[00:26:38.170]We would love to know what's going on out there
[00:26:41.240]and we would love to hear from you.
[00:26:44.130]Thank you, Beth, for your great adventure today.
[00:26:47.230]Let's review really fast what she taught us though.
[00:26:50.300]First we learned about the four types of housing
[00:26:52.460]for egg-laying hens.
[00:26:53.840]Cage, cage-free, free-range, and enriched colony cages.
[00:26:59.390]While there are many drawbacks and benefits for each type,
[00:27:02.460]one thing is for sure the farmers care for those birds
[00:27:05.450]by providing water, food, and shelter.
[00:27:09.040]Beth also taught us how the eggs
[00:27:10.910]get from the hen houses all the way to your table.
[00:27:13.730]Once they get to your house
[00:27:14.830]you can use them in so many different ways.
[00:27:17.110]My favorite is using them to bake brownies, or a cake,
[00:27:20.980]oh, or hard-boiled eggs are good too.
[00:27:23.380]Oh my gosh, there are so many things you can do with an egg.
[00:27:25.900]What is your favorite way to eat an egg?
[00:27:29.010]Well, that actually brings us back to our question page,
[00:27:31.550]now that I've asked you another question.
[00:27:34.140]Let's go ahead and take a few minutes
[00:27:35.410]to answer any questions that you know the answers to now.
[00:27:40.130]Do you have some questions left?
[00:27:42.860]We thought you might.
[00:27:44.250]You can post them on social media
[00:27:46.190]with the #NE4HEGGS, and we'll answer them,
[00:27:50.390]or for maybe a faster response send to your teacher.
[00:27:54.270]And if your teacher can't answer them,
[00:27:56.370]or unsure of how to answer them,
[00:27:58.470]they can send 'em to us and we will respond to you too.
[00:28:02.140]Now, before you go
[00:28:04.410]I actually have one last surprise for you.
[00:28:09.140]We were able to capture the video of a chick
[00:28:13.670]actually going through the process of hatching.
[00:28:16.180]So this chick here that you can see,
[00:28:18.160]there's some other ones inside of there,
[00:28:19.910]they're just hanging out just waiting to dry off
[00:28:23.010]before they get taken out,
[00:28:24.530]but we have an egg up there in the corner
[00:28:26.270]that is going through the process of hatching.
[00:28:28.770]So this chick has pecked through their air cell
[00:28:33.680]and has taken their first couple of breaths.
[00:28:35.810]And it's been pipping for awhile,
[00:28:38.300]which means cheeping inside the egg,
[00:28:40.230]and it started to peck a hole,
[00:28:42.820]or peck a line around the entire egg itself,
[00:28:46.930]and now it's ready to pop through the end.
[00:28:49.280]However, it gets really tiresome
[00:28:51.280]and it takes long breaks
[00:28:52.910]in-between because it gets so tiresome
[00:28:58.090]trying to push out of that shell.
[00:29:04.210]As you can see it's friends
[00:29:05.540]have lost a little bit of interest.
[00:29:08.030]They've kinda settled down.
[00:29:10.040]This one, or it comes back here in a little bit,
[00:29:11.860]but it actually pushed through
[00:29:13.750]and is now out of the shell completely, almost completely,
[00:29:17.120]it's still got his bottom end there in the shell.
[00:29:19.630]We just let it sit there and rest
[00:29:21.390]and eventually he'll kick that bottom part off.
[00:29:24.780]Once he does get the bottom part off
[00:29:26.400]we will let him continue to rest.
[00:29:28.560]As he lays in the incubator
[00:29:30.220]he will actually continue to dry off.
[00:29:32.350]His feathers will fluff up
[00:29:33.940]and then we will put him into the brooder box
[00:29:36.580]where he will have food, heat, and water
[00:29:40.070]accessible for him at all times.
[00:29:47.310]If you enjoy watching these eggs hatch
[00:29:50.850]one thing that you can do is actually goggle
[00:29:53.080]4-H Egg Cam, and you will be directed
[00:29:56.490]to our friends over in Lancaster County
[00:29:59.080]where they actually have a live egg cam going on
[00:30:01.840]and you can watch more of this.
[00:30:03.760]I hope you take the opportunity to check this out
[00:30:06.290]and maybe catch some eggs actually hatching.
[00:30:11.800]Thank you for joining us today
[00:30:13.600]on this final lesson of "Embryology 101."
[00:30:16.930]It sure has been enjoyable
[00:30:18.910]learning all about embryology with you.
[00:30:22.230]On behalf of Nebraska Extension
[00:30:24.280]we hope that you have learned about embryo development,
[00:30:26.990]how to care for eggs in an incubator,
[00:30:29.490]understand the traits that are passed on
[00:30:31.590]from parents to offspring,
[00:30:33.270]and know how eggs travel from Farm to Table.
[00:30:36.870]Thank you so much for joining us on "Embryology 101"
[00:30:39.710]developed by Nebraska Extension.
