So I was aiming for a 4x8FT chicken tractor but I realized that the amount of room for the run and the coop itself isn't enough. So to match it, I was thinking of a 4x4ft coop on top of a 4x10ft run. Will that work? I'm worried that the fact nearly half the run is covered by the coop that it may negatively effect the chickens. To put it clear of what I was thinking about doing is building a frame for the run and in the very back 4ft of the run (since the coop is 4ft long) put on extra supports and beams across it where I can put a piece of plywood (or something like that) on top of as the base, where I can put thinks such as walls on, creating the coop. The stairs would be underneath the coop. Anyway, is this a bad design? Also, as far as chicken tractors go, how do I make it level? If I have the wheels on the back of it and I set it down the very back will be slightly higher then the front. How would I fix that?
