How do chickens hatch?

Hens brood in their nests. Hatching chickens with hens is widely used for farmers to raise chickens by themselves.

The required equipment is simple, the management is convenient, the hatching effect is good, and the hatched chicks can also be led by hens, thus reducing the brooding link; However, the hatching rate is small, which is easily restricted by seasonality and is not suitable for specialized scale chicken raising.

When you shine a flashlight on an egg, you can see the changes inside it. If fertilized, there will be blood vessels in the egg.

Holding a nest, also known as love nest, is a reproductive instinct of birds. Generally, when the environmental temperature rises gradually and the amount of eggs laid is relatively high, the phenomenon of nesting will occur. Moreover, storing multiple eggs in the henhouse can also induce hens to hold the nest.

The so-called "few eggs" are eggs that hatch without fertilization or eggs that hatch unsuccessfully. Generally speaking, "few eggs" can't hatch chickens.

Extended data

1, double yellow eggs can't hatch chickens. The space for growth and development is very narrow, and the eggshell thickness of double yellow eggs is usually much harder than that of ordinary eggs.

2. The embryo in the double yellow egg has survived successfully. When a young bird breaks its shell, it can't turn its body because of the narrow space, and it can't break its shell successfully, which will also lead to the death of the young bird.
