We're finishing our coop for 10 hens. It's smallish so we have to be efficient with use of space. It's a 5' x 5' room with 3 nest boxes built out to the exterior. We're thinking of doing one level of L shaped roost up high with a ladder of sorts to access it. I have two questions: If we do the roosts close to the walls, how close is too close for them to be comfy? And how much width of poop deck do we need to have on either side of the roost to catch that good stuff? Thanks!
