I am thinking of adding to my lil backyard barnyard! I have about an acre of land and already have some hens and roosters. Thinking of adding either a couple of small breed goats or sheep that will graze and keep the grass under control. My eldest daughter loves goats - but we had one when I was younger and I don't remember them eating much grass. .. roses, bushes, etc - but not much grass. I wouldn't mind a couple of smaller friendly breed sheep. Or maybe even a goat and a sheep together (wouldn't mind goat milk eventually) Any recommendations?
