In poultry farming, early feeding is the ad lib availability of feed and water for day-old chicks from the moment of hatching from the egg.. Early feeding has a positive effect on chick performance because development and maturation of important organs is not retarded post hatch, but continues.
A female mallard duck incubates her eggs. Egg incubation is the process by which an egg, of oviparous (egg-laying) animals, develops an embryo within the egg, after the egg's formation and ovipositional release. Egg incubation is done under favorable environmental conditions, possibly by brooding and hatching the egg.
The sitting hen will leave the nest once a day from 20 minutes to one and a half hours, and will then defecate, drink water, eat and sometimes bathe. Once the eggs begin to hatch, it may take 24 hours for all the chicks to break through their shells. When feral chicks are born, they usually stay with their mother for about 10–12 weeks.
Poultry farming is the form of animal husbandry which raises domesticated birds such as chickens, ducks, turkeys and geese to produce meat or eggs for food.Poultry – mostly chickens – are farmed in great numbers.
Examples of precocial birds include the domestic chicken, many species of ducks and geese, waders, rails, and the hoatzin. Precocial birds can provide protein-rich eggs and thus their young hatch in the fledgling stage – able to protect themselves from predators and the females have less post-natal involvement.
In bi-parental care, the male provides food and the female is a caretaker. Both ensure the survival of the offspring. The female may care for her young by covering them to keep them warm, shielding them from the sun or from rain and guarding them from predation. The male may also feed the female, who in turn regurgitates the food to the chicks.
