According to the theory of biological evolution, chickens do not always exist. They belong to birds, and birds and mammals evolved from reptiles. There are many differences between reptiles and birds, but one thing is the same.

They are all oviparous. Reptiles such as snakes, turtles, and even dinosaurs lay eggs. That is, before the appearance of the chicken breed, its ancestors already had eggs.

The most primitive chickens are produced from these eggs. However, the chicken before the appearance of the egg is not the so-called "egg", but the so-called another egg.

Chickens didn't always exist, they belonged to birds, and birds and mammals evolved from reptiles.

Domestic chickens are derived from wild raw chickens, which have been domesticated for at least about 4,000 years, but it was not until around 1800 that chicken and eggs became mass-produced commodities. The types of spring chickens are turkey, black chicken, pheasant, etc. And the rooster is also one of the 12 zodiac signs.

Poor cold resistance. The hatching chicks, the body temperature is lower than the adult chickens 3, it takes 10 days to reach normal body temperature, and the chick fluff is short and thin, can not keep out the cold, so the adaptability to the environment is not strong, must rely on artificial insulation, the chicks can grow and develop normally. Generally, the body temperature of chickens is between, so it must be warm in winter and cool in summer, and raised in a well-ventilated environment, in addition, the digestion of chicken Qifan is short, the metabolism is vigorous, and the growth and development are fast, so it is necessary to feed sufficient nutrition and easily digestible feed to meet the needs.

Weak resistance. Chicks, in particular, are susceptible to harmful microorganisms.

The head of the chicken is thin and the feet are thin, the mouth is yellow, the feet are yellow, and the fur is yellow. The rooster has a single crown, and the crown and beard are large and bright red. The beak is short and broad, brownish-yellow, the neck feathers, saddle feathers, and sickle feathers are golden yellow, the bridge and yoshik dorsal feathers and wing feathers are dark yellow or reddish-yellow, and the thorax and ventral feathers are pale yellow.

The main tail feathers are black and flashy, the shins and claws are orange, the inner and outer sides of the tibia are dotted with erythema, the feet are short, the hen has a single crown erect, the crown is medium in size, the crown, mustache and earlobes are bright red, and the whole body is yellow.

The whole tail wing is ostriches-like drooping and not upturned, the annual egg production is 110 130, the egg is suffocated and weighs 45 grams, the eggshell is mainly light brown, occupying, and there are also white and brown.

Here's how chickens came to be: according to the theory of biological evolution, chickens didn't always exist, they belonged to birds, and birds and mammals evolved from reptiles.

Reptiles and birds have many differences, but one thing is the same, they are all oviparous animals, such as snakes, turtles, and even reptiles such as dinosaurs laid eggs, that is, before the appearance of the species chicken, its ancestors had eggs.

The most primitive chickens were born from these eggs, except that the eggs before the chickens appeared were not called "eggs", but some other eggs.
