Life cycle of chicken

There are nearly 20 billion chickens on earth The average life cycle of a chicken is about 10 years, which is far lower than the average life span of nearly 80 years Life begins when chickens spend the first 21 days hatching in their eggs After a week's development, it becomes an embryo with beak, wings and neck to separate the head and body In the process of development, hair follicles and feathers begin to form The hen murmurs to the chick in the egg, which is why she can hear the chick reply a few days before hatching The eggs in the incubator need to be kept at 37-39 ℃, and the air humidity is 50% to hatch Incubators need to be well ventilated because eggs produce carbon dioxide and absorb oxygen In the first 18 days, it is necessary to turn the eggs at least three times a day to ensure proper development of the chicks Leaving the egg on day 17, the chicken moves to the hatching position The beak, previously hidden under the right wing, extends towards the egg membrane On the 20th day, the chicken pierced the diaphragm and took the first breath of air from the egg airbag After pecking the egg shell with the protruding beak, the chicken broke the shell 12-18 hours after the 21st day The chicks just hatched from the eggs are wet and need about an hour to dry The chicks should be dried before transfer to the preheater Early life hens take a long time to protect their chicks from growing feathers Hens always keep their chicks close to themselves, teach them to find food and avoid other adult chickens If the chickens are hatched in the incubator, they should stay in the incubator at 37 ℃ until the feathers are rich The chicks hatched by the hens eat the small food specially found for them, while the chicks hatched indoors depend on the mashed food you provide Supply water in a shallow container that will not submerge the chicks In the outdoor environment, the hen is always vigilant to watch her chickens, but you should also keep the chickens away from the pond or other places prone to drowning Young chickens are ready to be raised on their own when they are six weeks old and covered with feathers They should be provided with enough hiding place to avoid adult chickens in the field until they find their own place Little hens little hens may start laying when they are 16 weeks old A few days before laying the first egg, it will form the conditioned reflex of squatting, with wings stretched out and lying on the ground at the same time This natural instinct allows the rooster to climb on her back and inseminate her eggs Her first little egg is called a little mother egg Eggs will grow larger as the number increases At this time of life, hens should be fed oyster shells or other sources of calcium for nourishment The cocks will crow when they grow to 10-12 weeks to prepare for the control of the farm and the domination of the hens His crowns darken, and the rainbow feathers on his tail form a sickle The feathers on the neck and shoulders are long and pointed and glow blue or green when the sun shines Adult chickens can live for 8-10 years, but a drop in hormones after age 3 means fewer eggs are laid and fewer chicks are hatched Old hens lay large eggs, but with low frequency By the age of five, she may stop laying eggs altogether You can tell if it doesn't lay any more by touching the pelvis between its legs If the separation is wide enough to put more than three fingers, it means that the egg is still laid But if you don't lay an egg, there's no room for one or two fingers in the middle Cocks also rarely chirp when hormones drop, and their crows and feathers fade as they age.
