The Chicken sits down to hatch eggs after laying 20 - 50 eggs. The duration of incubation of eggs is 21 days, but due to climatic characteristics, chickens may appear on days 20 - 23.
After the chicken sits on the simulated egg and does not leave the nest for 1 - 2 days, you can put real eggs under it. The number of eggs in a clutch depends on the size of the bird itself, usually 11 - 15 eggs.
During incubation, the chicken rises from the eggs several times in order to eat. The brood Chicken is afraid to leave its nest for a long time, so bowls of food and drinking water should be kept close to the brooding site.
