ok I am almost done with the coop and am contemplating a change. I think I am going to leave at least one wall open (wire) to help maintain some cooler temps. But I had it all planned out for four walls and now need to readjust the interior. with that said here are the questions: 1. can i put the nest boxes (3) closer to the floor and put the sleeping roost bar above the boxes? 2. would the roost and/or nest boxes be better on the solid wall opposite the open wall? or would it be ok on one of the side walls? thanks for any advice given. you guys have already been a big help in my first endeavor with chickens.
