So just what is a brooder and what is it for?
A brooder is a self-contained area that provides a warm and safe environment for chicks. The extra warmth is supplied by a heat lamp or electric hen like the one keeping these chicks warm below. A more up-to-date option is the electric panel, which consists of a heated plate on legs. The chicks go under this for warmth, as they would with a hen, some even have a shroud around the edges to mimic the hens feathers.
