I moved to a quiet twenty acres on a mountain in Virginia in August and got chickens in October. My chickens free range. I put them into our very secure chicken barn just before sundown and let them out when I wake up. In the few months I have had them, they haven't gone further then a few hundred feet. They do, however, have their water supply and food at home. The rooster watches out for his ladies and sometimes goes on further forays with them, but usually rounds them back up to stay closer to home. He is a good rooster. Maybe this will change in the summer. My in laws had chickens on this land for more than twenty years and there was never a casualty until one chicken decided she didn't want to go back in at night. Apparently she roosted in a tree and lasted about a week. Pretty good, considering we have visibly active coyotes, wild cats and bears around here.
