Ok so I put together a 29"W x 16"H x4'L box (ends open) and now I don't know what to do with it. It goes on the top of the bottom coop that I have made from a massive dog crate. I was going to use it for the nesting box, but 4ft is a big long to reach in to get the eggs. Unless I put a open door on the one end..... however what to do with all that space. Any ideas?? I've tried to look at some coop designs to get ideas, but now I'm clueless.
