Not every hen will hatch future offspring. Often this is due to the fact that previously a person diligently drove the bird away from the nest, which led to the development of an appropriate instinct. But you can choose and prepare a bird that will take care of hatching eggs.
The organism of the future hen does not require special preparation. But all chickens need to be fed rationally so that the eggs are with a dense shell. To do this, include crushed shells in their diet (it should be in powder form). Specialty stores also sell food fortified with minerals and vitamins. After about a few weeks, the shell will become firm, even if it was fragile before. But do not forget to observe the dosage, otherwise it will be difficult for future chicks to break through.
As a brood hen, choose the one that most often tries to hatch laid eggs. If your birds do not show much interest, and previously you regularly drove them out of their nests, you will either have to buy another chicken or raise a hen yourself. On average, birds are ready to evaporate eggs at the age of 1 year.
Hens that behave restlessly, and also cackle loudly and quickly run away from the nest when a person approaches them, are not suitable for incubating chickens. Place dummy eggs in the nests to select the right bird. Observe, that chicken, which practically did not leave the clutch for several days, is optimal for long incubation of offspring.
Gently change the eggs at sunset and add 13-15 real eggs. It is advisable that the chicken does not notice the change, otherwise it may stop caring about future offspring.
Do not put a brood hen in the house with other birds. They will interfere with her hatching eggs or may even peck at them. Feed the bird as usual. Make sure there is always fresh water. Place the feeder and drinker in the immediate vicinity of the nest. It is also advisable for hens to swim in an ash-sand bath. Mix these two ingredients in equal proportions and pour into a wide but shallow basin or just on the floor. After about three weeks of incubation, small yellow chickens will be born.
