Attached are pictures of the enclosure I have my five RIR's, five Brown Leghorns and two Black Giants in. It is between 4 1/2 and 5 feet tall. How long will they be able to stay in this without a cover? They are 1 1/2 weeks old. Also by the way, does anyone know if Black Giant hens have spurs? My two chicks have tiny little bumps there.
