We have a dog kennel that's covered that we want to use for chickens. My question is do we need to build a little house in it or can we just put the roost and nesting boxes right in there? We live in a mild climate, but it does get hot in summer. Very rarely freezes or snows. Substantial amount of rain. The top is completely covered with a roof but we will cover any openings with more fencing to keep predators out.I tried to upload a picture but it didn't work.
