The term 'brooders' is used to refer to HENS, which are female chickens. HENS are kept for their eggs, meat, and sometimes as pets. They are also used in some cultures for religious ceremonies. Brooders are HENS that are kept for the purpose of hatching eggs and raising chicks. They are usually kept in a separate area from other chickens and are provided with extra food and warmth to ensure the health of the chicks.
