My darling brother finished my brooder today - now if the girls would only start laying again!! I found this bathroom cabinet on CL a couple of months ago. He punched out the door inserts and replaced them with plexiglass, put a hinged lid on it, and legs with wheels. Inside dimensions are 46' x 20".
Hens go broody when you don’t want them to… and won’t go broody when you do.
