This is the design I'm thinking of. I want about 6 hens, which I think so be an easy number to start with. I'm also going to be planning a run for them too. The back will be where they can rost (sp) and than they'll have the laying box in the further back. They'll have a fenced in area to hang when their not in the run. I'm thinking of venting on the sides for ventilation. The side will open for cleaning. The lid for the nesting box will open from the top for egg picking and cleaning. The bottom will be fenced too to stray off predators from digging in or the chickens from digging out. I'm new at this so slowly learning. And yes I know I need beams across the middle for more support.
