A brooder is a device or structure used to keep newly hatched chicks warm and safe during their first few weeks of life. It is essential for chicks to have a source of heat as they cannot regulate their own body temperature in the first few weeks of life. A simple brooder consists of an infra-red heat lamp with a hood over it to direct heat toward the floor, and a brooder guard, which is a cardboard or wire mesh ring to keep the chicks confined to an area near the heat source. The temperature inside the brooder should be monitored and adjusted as needed to ensure that the chicks are comfortable and healthy. Other important features of a brooder include a light and heat source, security, and a source of clean, fresh water. There are different types of brooders available, including area brooders and brooder lamps, and they can be purchased or made at home.
