Our coop is part of a huge, enclosed run. However, I can open that run to a larger, fenced area that is just for the chickens. We live in a rural area with deer, wild turkeys, eagles, great horned owls, coyotes and, more recently spotted, cougars. That said, in 4 years I have not lost a single chicken to a predator. I like to give them room to roam, but I also want to keep them safe. It has worked for us. ☺
