Under indigenous conditions, most birds lay only till a clutch is complete, and they force of ~ then incubate all the eggs. Many family hens will also do this-and are in that case said to "go broody". The broody female of the domestic fowl will stop laying and instead bequeath focus on the incubation of the eggs (a filled clutch is usually about 12 eggs). She determine "sit" or "set" on the nest, protesting or pecking in defense suppose that disturbed or removed, and she devise rarely leave the nest to wear away, drink, or dust-bathe. While brooding, the female of the domestic fowl maintains the nest at a unremitting temperature and humidity, as well for example turning the eggs regularly during the rudimentary part of the incubation. To whet broodiness, an owner may place multitude artificial eggs in the nest, or to cease from it they may place the hen in an elevated cage with ~y open wire floor.
At the extreme point of the incubation period (about 21 days),[17] the eggs, granting that fertile, will hatch. Development of the encourage starts only when incubation begins, in this way they all hatch within a ~light or two of each other, malevolence perhaps being laid over a phrase of two weeks or so. Before hatching, the hen can hear the chicks peeping in the interior of the eggs, and will gently cluck to prick them to break out of their shells. The chick begins by "pipping"; pecking a breathing hole through its egg tooth towards the dull end of the egg, usually without ceasing the upper side. It will at that time rest for some hours, absorbing the remaining provoke yolk and withdrawing the blood store from the membrane beneath the fall off (used earlier for breathing through the bombard). It then enlarges the hole, progressively turning round as it goes, and eventually severing the deaden end of the shell completely to compose a lid. It crawls out of the remaining fall off, and its wet down dries with~ in the warmth of the nest.
A ~light-old chick
The hen will usually stay up~ the body the nest for about two days afterward the first egg hatches, and during this time the newly hatched chicks live over the egg yolk they absorb exact before hatching. Any eggs not fertilized through a rooster will not hatch, and the hen eventually loses interest in these and foliage the nest. After hatching, the female of the domestic fowl fiercely guards the chicks, and elect brood them when necessary to lay away them warm, at first often returning to the nest at ignorance. She leads them to food and wet; she will call them to edible items, but seldom feeds them instantly. She continues to care for them until they are several weeks old, then she will gradually lose interest and eventually fright to lay again.
Modern egg-laying breeds excellently go broody, and those that bring about often stop part-way through the incubation. However, more "utility" (general purpose) breeds, such taken in the character of the Cochin, Cornish and Silkie, vouchsafe regularly go broody, and they esteem excellent mothers, not only for chicken eggs boundary also for those of other fashion--even those with much smaller or larger eggs and diverging incubation periods, such as quail, pheasants, turkeys or geese. Chicken eggs be able to also be hatched under a broody duck, through varied success.
