I am trying to plan for a possible builder coop in the late Summer. I know that the way I se up, there is a lot of wasted space, but that is okay. If I change from breeder pens later on, I can remove the pens and have a large coop for anything. This is a big part of the plan. Each design has space for a brooder, at least 2 pens, a run, and look okay. The first one is like Buster's coop under construction. The second is exterior like the layer lodge, minus one "wing" if that makes sense.
