If you look at my page you will see my set up. I guess I will have to do away with the roost sticks. There is no room for them to roost in their house.
I would try and stick some sort of perch in the coop, even if it's barely off the floor. I couldn't tell from the pictures but if there are more than 2 nesting boxes you could make some more room by getting rid of extras. Two should be plenty. Lucikly you're not trying to get backdoorchicken to roost in your coop so I wouldn't worry about repainting it. If you like it, keep it!
