Love the nesting box!  I'm using it right now for my brooding box until my little ones are big enough to go outside. I wish the roosting bars weren't so close to the tray but for the size that's about the only place they can go.  I'm going to make another roosting area once I get them outside.  I'm not sure how it's going to hold up in the weather at this point.  I'll be reinforcing the outside with weather paint and caulking.  I'm purchasing a bigger run for more space.
