Brooding involves rearing baby chicks-as newly hatched chicks do not fully develop the thermo-regulatory mechanism and homeostasis. Thus, it is often difficult to maintain the body temperature properly for the first few weeks of life-as birds might be subjected to chilling if not properly introduced to a regulated heat source.
Brooding can be classified into natural and artificial brooding.
Natural brooding: Involves the help of broody hens after hatching, up to 3 to 4 weeks of age.
Artificial brooding: A large number of chicks can be reared in the absence of broody hens.
