Dh made a small coop before we got chicks when I went out of town (so, without consulting me and without any research). He made it about 4x4 and the highest part of the roof is about 6ft, and it slants downward to about 3 1/2ft (this is where the nesting boxes are). The floor is 1/2in hardware cloth and it's raised about a foot. I've told him that it is too hard on the chicken's feet, but he doesn't want to redo anything. Also he thinks they will just spend most of their time in the run (16ft x 8ft) and then sleep on the roots, so it doesn't matter. I'm worried about winter, we live in utah, and while it usually doesn't get bitterly cold here, we do get a lot of snow and it's often in the teens/20s so I'm thinking they won't want to spend a lot of time outside. Wouldn't there be a draft that would be bad for them? Could we just lay down some kind of flooring on top of the wire? Also, I don't think it would be too hard to extend the length of the coop, so do they need more room? This coop will be for about 4 hens. Also, the roof is just wood right now (NOT water proof), so I know we need to put something on it so the girls don't get wet. DH doesn't want to do shingles. Any other ideas? Thanks!
