Just built a broody pen/brooder in the storage area of the Delaware coop, especially made for my banty Cochin, Shadow, who has just gone over the edge, LOL. This is about 38" long and 28" wide, inside measurements and 24" tall. There is hinged lid as well as a door on the end for ease of maintenance. Because it's hardware cloth all round, it can be used as a safe outdoor brooder. Tonight, we move Shadow on the five eggs we want her to hatch.
