I have 4 Barred Rocks and 2 RIR and I can't let them free range due to city ordinance. My coup is 4x4 top roosting area as well as a 4x4 lower area and 2-6' runs. One on each side. Is this enough room for them? It is not mobile. I am adding a run that I can let them get fresh grass and new area and close one area off at a time to regrow. Any suggestions?
