a man to present a new spinal implant. well, the ground breaking device change lives after paralysis. to morrow to day. in 60 minutes on d. w. as you've got any issues with thoughts they will grey, you will be able the blue . oh a this is helena. a very strong minded chicken. she's curious and always on the move. and she's yearning for some human company.

much might be sometimes like he doesn't even know she's the gentleman yet. can you store? helena isn't just any chicken, though. she is one of 26000000000 of her kind on our planet. the chicken and the egg, an evolutionary success story. although chickens play a role in our lives almost every day in one way or another, most people know very little about them. ah v. hm. it is a little like love at 1st night. the 1st time i saw helena is in hop. ah, this is helen as owner lisa, or rather dr. lisa, yom, agricultural scientist, chicken's or her work, 2 egg laying chickens to be precise. ah, there's a gaping void and helena's nest once again. and yet the whole point was for her to

lay eggs and hatch them. but helena didn't immediately start laying eggs. when unhappy are men, she started hoarding the other hands eggs in the middle of the winter. when i looked under helena, i found to 12 and i it was a mix and none one hasn't. yvonne she ended up hatching him. he kept saying, how's the brutus she nabbed the eggs from the 7 other hens she lives with. and lisa young's garden, all her chickens had been facing dire fates for you. i'm not, as we have a loss of welfare cases, take chancy. here she's from approved of laying hands out. they were at slaughter house, and shanty escaped from the transport box pocket. ah, these dwarf or ping tens are missing one spike in their crowns or combs. they were supposed to become feed for the zoo. ju nano was the only white hen and

a flock of brown ones. and the others bullied her. she ended up completely feather las and it looked like she might not survive. but now she lays more eggs than all the other hens here. juna is definitely no charity case. ah, and the young family gets to have fresh eggs almost every day along with amazing chicken facts. ah, i guess the egg yolks are among the biggest biological cells name to us. and that will send the gym, sell where the chick develops wood on august the and vic and exxon one a fitness nutrient rich animal laced mr. la dunn's gun fee, the national for that $103.00. they have everything a chick needs to grow up healthy. and what's good for chicks is highly nutritious for all of us. chicken eggs contain particularly valuable protein

that our bodies can easily transform into its own. along with minerals, vitamins trace elements and unsaturated fatty acids. but what about collateral? the latest research says healthy people don't have to worry but nature didn't come up with eggs as food. they're actually highly sophisticated incubators. and they're very tough. little chicks have to put a lot of effort into picking their way out. jobs will not that the not to x are a real marvel of nature, but i, english is on the shelves are critical to protecting the changing auntie hannah, after all, to be off. the hens sits on the egg laundry takes it several times a day. i notice i was attached to withstand a great deal for diamond and it's so tough in them that the checks even have

special teeth cold. thank teeth to break, open the eggshell ha oft suppression but how can eggs be so strong top them once and they're broken. lisa young decides to stress test an egg herself . i'm pressing really hard trying to frank it messed up. i wouldn't have thought it would be so difficult. i really thought i'd busted open, but even with all my strength, i can't should i stand on that often? no, maybe not. that wouldn't help us understand why eggs seems so fragile, but are extremely sturdy at the same time. it's their shape. ah, their curvature helps distribute force as evenly across the shell. and that's in part due to their structure. and egg shell is normally point $3.00 to point $4.00

millimeters thick and made almost entirely of calcium carbonate. the main ingredient and limestone, so it's very strong. it's made up of many little pillars called crystals, densely packed together. they form a sturdy structure. and the numerous pores lend the shell a degree of elasticity, but they also help the egg breathe, carrying carbon dioxide out and bringing fresh oxygen in. and the air's humidity penetrates the egg, preventing it from drying out. but let's come back to these little ones hatching here. ringback layer offspring at the scientific poultry farm and almost kitchen biologist ma hika phelman is still moved by the experience even after all these years. but these chicks here don't look all cute and fluffy.

are they doing okay. and he, unfurnished, london, i can't within 24 hours, the freshly hatched checks look completely different because they really fluff up just like typical checks and they have to keep up with their mother. then they're already agile can handle walking longer stretches and can eat and drink. so they're basically ready to go within 24 hours. the status on this day several different breeds of chicks hatch, including baby dwarf silky chicks and german creepers. scientists breed old races here that have become very rare for research or not as my and sometimes we simply have them here because they look so sweet um, ah, ah, in europe there are officially about 200 different chicken races. all shapes and sizes and colors. but are they really all interrelated? you know,

the via arms and the chickens. we have here as pets are domesticated animals that once developed from wild ones, we can see the wild rays here, the red jungle fowl. ah, the red jungle fowl is a tropical bird from the phase sienna di, family, and thought to be the ancestor of common domesticated chickens. at 1st glance, these extremely timid animals hardly look any different than the chickens we know today. as to thank you, decide what really set them apart is their size. there are of course even smaller chicken races, but when you look at them they wouldn't be much use as roast chicken. i and they also don't lay many eggs, maybe $24.00 a year. so not much compared to laying hands, which lay over $300.00 eggs a year. yeah. wild chickens originally come from south and southeast asia. but it's hard to say just how long chickens and humans have been living together. one theory

relying on fossil evidence suggests that chickens were 1st domesticated 8000 years ago. but not all scientists agree. what does seem certain is that the indus valley civilization captain bred chickens from 2500 to 2100 b. c. traders then brought chickens to the middle east by the silk road. and to egypt around $1475.00, b. c. chickens then spread across greece to italy at around 500 b, c o r ancestor as valued the animals for their magnificent coat of feathers. but not so much for their eggs and meet the bird served spiritual and medical uses and battled it out in cockfights. the romans were the 1st to raise chickens in large numbers as a source of food. and they spread domesticated chickens throughout europe. only in the 20th century did farmers began breeding chickens meant to provide

either meet or eggs the resulting hybrid chickens. crossbred from pure breeds are meant to yield maximum food as cheaply as possible. one hybrid line provides meat and the other eggs. and at the end of their lives, meat for soup ah, researchers and breeders have been extremely successful, increasing the amount of eggs hence could lay to over $300.00 a year. conditions for raising chickens have also seen improvements. the cost of feed as dropped stalls are automated, and minimal space is required per hen. mm. conventional battery cages may be prohibited in germany now, but demand for the cheapest possible eggs has kept on climbing. in 2020 the average german consumed $239.00 eggs for a total of $20000000000.00 nationwide. that may sound extraordinarily high,

but it's more than just breakfast eggs because even if we may not notice them, eggs are present in all kinds of foods. readers have pushed hybrid laying hands to their physical limits and that impacts the animal's health. lisa young has been investigating the topic, for instance, when it comes to sternum damage as palestine. the sternum is like this in the hands of the hands stomach when it's standing. he is the hand cook and has the tail and now we can see all nice little thump on the stone em decline properly. he. a allah, these, anthony earl fratkin is in dawson, and i often see things like this of thea. unkindness on asking us this hand must have been in a lot of pain as my ha, oh sh manslaughter. oh,

today lisa young is at the state owned franken housing farm, a training and research site that belongs to the university of castle. she's researching organic chickens for the future. the animals do more than produce eggs . they're also like little lab assistance. and these are no hybrid animals, their dual use chickens yielding both eggs and meat de leon, and this in vinegar. they don't lay quite as many excess, conventional commercial, hybrid or more like 240 instead of 300 a year and gigs up to die. oh, nuts. and since they lay few an egg, they have fewer stern and fractures giving as i allies. ah, these hands are fortunate, not only do they enjoy top rate production conditions, but they also have roosters in their stalls. the males eat a lot yet have little market value. what a luxury and affinity you signed roosters almost exclusively on organic thumb, even because they're an enormous cost factor to try lay eat a lot,

but don't lay eggs. the thought is, they're not profitable. my, my bank asked my guarantee in the idleness i got. these are they come down the floor and ensure the chickens go out needing to less behavioral disorders. like picking feathers, we'd have to feed because they're busy performing the natural behaviors. if they're species instantiating chron rooster's are important. i received some tire. ah. so they're not a mere luxury, and helena would be happy to have a male around to protect her again. you have now somehow used to have arista hung into the 1st one would wake everyone up at 3 in the morning. and i don't mean just ask you would wake all the neighbors tune up your stomach exit. yeah. and then we had another room to the guard at the flock so well it would attack us and wouldn't let us approach the hens. meta him, we got rid of that one too. he had numbered on all hopkins. and these hands also

have to live without a rooster. now. up until a week ago, there were still 3 young roosters in the connell families yard. they got along well until a fight broke out between them over the hens, peace and harmony, never returned. and so the roosters ended up in the frying pan. the family's passion for chickens began with a birthday surprise. they got to borrow chick, and there was no turning back. they just had to have another 5. that was the plan. anyway. i go ha, ne canada of no one i know stuck to 4 or 5 chickens. once you've caught the chicken bug, there's no going back. if you'd see it is minus the 3 roosters. they now have 10 adult chickens and another 14 chicks hatched 2 weeks ago. when get swanson, i always if we had 20 eggs and end up with 10 roosters, we'll have to slaughter them at some point. no 9, we might keep one when on shore, it depends how the boys behave because especially with roosters like them. it's

hard, of course, we basically raised them is it's me, they sit on your knee, they fall asleep in your hand. and you have to decide at some point in my wilma, your life's going to end to night and ended on being because to night i'm going to slaughter and eat you as it sounds so extreme escalade. but the little ones will have a really great life for at least half a year. and that's at least half a year longer than the brothers of lane. hens normally live because they're immediately sorted out and killed after they hatch. that's the dark side of breeding to attain maximum egg yield. the hens, brothers are mere waste products. $45000000.00 male chicks die each year in germany . it's not worth it to raise them to adulthood. they eat a lot, but don't gain weight easily and only a 3rd of their meat is suitable for human consumption. but killing mailed chickens will become illegal in 2022. farmers will have to raise the roosters. you come

on us now. can you even manage that cost effectively by this? because the most expensive part of raising animals is the themes and types. and langham is the selected for high and killed and not that producing needs to be interesting funds. and there is one work around already determining the sax inside the egg. after 9 days, analysts extract some liquid, but it's inside, remains untouched. they utilize a bio engineering procedure to show which eggs contain a mail embryo. afterwards, those eggs are sorted out. the method is already being used. another approach involves special light beams and is said to be effective starting from day for the res, penetrate the egg and are reflected back out. then systems analyzed the reflected light, showing whether the ag contains

a rooster or hence leo land and damita certify organic farms. they reject this kind of egg selection. they want male animals raised as well. 500 eggs have hatched, and eunice dawns hatchery. now the chicks are being packaged for their big trip to the breeders are fine. okay. but these aren't just any chickens there. breast gal was dual purpose chickens to how we fastened the roosters that these ones don't fatten up as big as normal broiling, but they don't have to either. the hens lay a lot of eggs. i don't have to lay 330 of them, but they lay quite a few years old. and we can make good use of both products once. since we don't have such high yields, we don't need that much feed either. so that makes for a lot of birds with one stone le le dual purpose chickens are still a nice product for now. and the quest for the organic chicken of the future has

only just begun. ah, jonas dawn relies on old races and new cross breeds. his animals are meant to be tough and healthy. there is no question about it. his eggs and meat are more expensive than if he were to raise hybrid animals. but there are an increasing number of consumers who want to stop supporting factory farming. broiler chickens are custom bred to yield maximum meet and they can be male or female. the goal is the lowest price possible. thus isde formula for the theses, the formula for a perfect rosa chicken window, thousands of punch cards, a used to find the chicken with ideal characteristics, giving input it's supposed to reach a ready to eat white as quickly as possible. using minimum fade, the chicken shouldn't be under or overweight, because that would negatively impact the processing workflow. factories like these continuously boosted their chickens productivity. to day it takes just $28.00 to

$30.00 days for a chicken meant to be roasted to be ready for slaughter. while those bread for chicken breast take 42 days, i use him to snatch a babys went to school. escrows'll systems can't ha yeah well when they gain so much weights, they fast that bones the sin, they winked. they can't always carry that body. his guns talkin, these chickens are 7 weeks old. conventional boilers would already be passed to their slaughtering age and halt, organic poultry farm and vincent housing. the clock ticks more slowly. the chickens live for at least 12 week. the parents are also hybrid animals, but they're crossbred so that they grow and gain weight more slowly. the chickens have more space and daylight than many of their kind. they get to head out into the winter garden, eat organic feed, and always have fresh water. busy busy busy in the end, an organic chicken often costs $3.00 to $5.00 times as much as

a conventional one. and few are prepared to pay that price. just 2.6 percent of poultry farm is organic and whether organic or not, we're eating increasing amounts of white meat. it's considered healthy and low fat, and many would prefer to just not think about how their tasty chicken breast comes from an extremely sensitive and friendly animal. ah, as a skip tonight is ins, is it so, tallie, some chickens are very trusting and friendly. i'm sure you can grab them, hold them in your arms and pet them installation for a lot of chickens enjoy it and they'll just sit there and it suddenly my, they closed their eyes and a really cuddly, you know, and they recognized their people. and so they can tell whether it's me walking past the fence. so some strangers, i'm taunt, hope i lost ah, more and more people want to know where their food comes from. and how well the

animals live. owning your own chickens is becoming more popular. houghton bag based farmer muscle image opted to get his own in 2018. ah young bunch cell phones as well. i can, i am at some point when you we wanted our own eggs and we had a little stole and some grassy free space. they were about 20 chickens in it, and then i thought actually i don't like this because they're always in the same grass. that was we decided to get our 1st mobile stole and stood and asked mobile style. and she's now they have to mobile stalls and $350.00 chickens. and they're constantly on the move. ah, they change locations almost every week so that they always have fresh grass. they're outside in all kinds of weather where they can pick and scratch around like chickens do. ah,

and they feel safe with the billy goat and it's family by their sides. the goats keep away, the greedy claws of birds of prey. yet dignified sun relative grow. it's a pretty big rescues and since we're moving around and often in areas with trees, where buzzards or other birds of prey dwell under a cry, fogel out and, and they might sometimes snap up a chicken, comes off from off or come, doesn't wound on cold, but what a terrible way to go. but hold on before we wrap things up. one last important question. what came 1st? the chicken or the egg? yeah, this is what a silly question, but really i have no clue monkwood. researchers have been trying to answer this question for centuries. from a biological standpoint, the response is simple. first came the non chicken, because chickens are birds, birds evolved from dinosaurs. and dinosaurs were reptiles,

which evolved from amphibious amphibians came from fish. and they all lay eggs. that means eggs evolved much earlier than chickens did just not chicken eggs. but even the happiest chicken has to die one day. and until now, that generally meant off to the slaughter house of the tourist, for even their death is fully automated. they move through a machine, the machine stuns them with an electric shock. i'm slow tis i scolds and plucks them with c. ah, the procedure hasn't changed. much over the course of time, even the final step is largely automated and extremely effective. few alternatives have surfaced for commercial farmers. almost a challenge of lands on this is mill. you have to remember it's a farm animal and they're ultimately supposed to be slaughtered. i try to provide the chickens a dignified passing, living. oh, look,

live that's why marcell emmelyn has been driving his custom designed slaughter mobiles through hesser since summer of last year. poultry farmers no longer have to squeeze their chickens into boxes for transport. the slaughter mo beale comes straight to their stall and that spares the animals, a lot of stress and injury. so cornish util quotes before i just catch the animals before mr. emanation comes in, and then they don't spend much time on the transport box on. so good have pleasant lives right up to the end of truth on. i'm going to inflame that chris on darcy is thus ready to yoga. islands are the biggest difference is that we hold the animals and put them under, individually, as the num craus left off that pile. that's different than that of factory slaughter house where chickens a hung upside down low and run through an electrified pool of water. electro. bob's

mit vasa was held off posse and con dustbins, a, if any of them pull up their heads and they might not end up being sedated, kind of and will be cut open and bled while fully conscious of them and foolishness . scalded flock, cut up. farmers have already to sell chicken after just a few minutes ago, and the customers at the farm store feel good knowing the animals had a pleasant life. little map with helena has many happy chicken years ahead of her. meanwhile, the quest to breed the super chicken of the future goes on a chicken that provides us with enough food, but doesn't have to suffer. but it's worth while to take a look back at chicken races of the past. this jani outman,

when it comes to climate change, for instance, we don't know what we'll need in 1020 or 30 years school. and that's why it's important to maintain diversity. these chickens may end up having characteristics the prove critical to us in the future. and that's why it's a god dream, the important to have and preserve these different races. i'm extreme refills, whatever the future may bring, one thing seems clear. helena won't be laying eggs every day, just every now and again. let's not forget, she's a different kind of chicken ah, [000:00:00;00]
