The development of birds can be classified into one of two main types: precocial and altricial. Precocial birds, like chickens, ducks and owls, hatch out with a warm covering of down feathers. A precocial chick can keep its body reasonably warm in the absence of heat from an incubating parent. Some precocial chicks can feed themselves soon after hatching.
