My chickens roam my small orchard freely, and they don't harm anything. The fruit won't hurt them. It would be one big chicken that could swallow a peach pit! When I can peaches, I put the skins and pits in a bucket and through it out for the chickens. They eat the peach skins, but really can't do anything with the pits. The squirrels end up hawling them off to eat.
