I just finished our brooder the other day and we've got our chicks in it. I put an extra light in it but I don't need it. It is 23" x 46" x 23" deep. It is split in the middle with a sliding door that is adjustable for the opening. It has an inline thermostat and 2 25watt bulbs. I want to put a window in it, and a door on the unheated side. the bottom is hardware screen, 3/4"slats, then aluminum flashing. Its working great and holding 90 degrees with no problem.
