We have kept our 12 hens/roosters in a run since they were about 2mo old. They are now 4mo old and I was wondering if they would be better off running around outside for a few hours a day. We do live on a farm, and I am worried about the barn cats, the traffic, even our dog. I thought about letting them run around inside or picket fence that we have around the house, but that is where our children play and I was wondering about chicken poop and the kids getting sick. I am so new to chickens so this might sound silly, but if I let them roam will they come back? Any input at all is really appreciated. Thanks!
