Here is my brooder "Prof. Beaky's Chicketorium". It's a 3x3 plywood structure with a second story of old wooden screen windows from a 1930s summer cottage. One of the sides is hinged to fold down for playtime and cleaning. It's up at hip level, sitting on a heavy cardboard bass amplifier box which was originally intended to be the brooder, but was not big enough. The chicks have a board, perches, river rocks and a sand tray and a forage cake. The screen guarding the heat lamp is stiff old metal stuff laced into the side screens with for security, no danger to the chicks. The light is also on a dimmer switch, mounted on the back outside wall of the brooder. That way I can adjust temperature without moving the lamp. The top is more screen. In this pic, the waterer is sitting on a plastic bucket lid for splash control, but as the chicks have grown, I elevated the waterer and feeder on bricks, cuz they love to scratch that deep bed of pine shaving into everything. I'll disassemble this and store it for future chicks.
