I plan on building a coop that would house at least 10 small chicken. However, they are all free ranging chicken. So, when it's time for sleep, they run under the house. I was happy about this at first, but months later they ended up sleeping on layers on poop. I want to avoid this by moving their sleeping area to a more accessible location. Anyone have any small or even makeshift coop ideas that would keep at least 10 small chicken happy?
