My wife and I are in the process of buying a farm. We plan on getting chickens again and I was thinking of either getting 2 goats or 2 mini donkeys. The coop will be a part of the barn where the other stock will live and then they can free range in the pasture together during the day. I've heard that that goats and other smaller stock are good at keeping predators away from the hens. has anyone else found this to be true?
