I've been working on a biddie box off and on for the last 2 days. Should have time to finish it tomorrow. Anyway, it's made of 2x4's, tin, plywood, and 1/4" hardware cloth. I built the frame out of 2x4's, the bottom is covered from end to end with hardware cloth. The sides are covered half way with tin and half with hardware cloth. The chicks can enjoy the sunshine or get out of the rain. The door is made of 1/2" plywood. I plan to put another door on the other side since it is so long. That way I'll be able to reach the chicks if I need to. What do y'all think about it? More pics tomorrow.
