What are your thoughts on wing clipping? We would like to free range our chickens, they are currently in a coop and 15x15 fenced yard. We would like to let them out into our much larger (acre or so) backyard which is fenced on three sides (5 ft) and the 4th side is a creek. Some have said we should clip their wings so it would be easier to corral them if we "needed to" and they also would stay out of the fenced gardens and the yard which butts up to the busy road. Others tell me that clipping wings will take away their natural defense from predators and it isn't necessary since they always come back to the coop at dusk. What are you thoughts??
