My coop is raised on stilts and very open because we have very hot summers and mild winters. The coop itself is 8 x 8 which follows the 4 sq ft rule for my 15 pullets who will soon be moving into it. We also plan to fence in the bottom portion under the coop and add roosts there and have a door to go back and forth from top to bottom so that even when they are locked in the coop at night they can go outside where it is cooler but still be protected from predators ( because then they would have to go through our yard fence, the run fence, and that fence to get to them). So my question is does that fenced in area under the coop count as coop space? I'd like to add 6-8 more pullets but I don't want to crowd anyone. They also have a spacious run.
