Hello. I was wondering if anyone could reccommend a good breed of sheep for us to raise for training our Border Collie. We live in north Texas (hot), have 100 acres and horses. We only want a very small flock. Prefer something fairly low maintenance, but prefer a breed that we would enjoy looking at, working with and being around. It would be an added bonus if it was a breed that has wool that we could possibly sell, or has lambs that would be easy to market. Thanks for any suggestions.
