Shetlands - easy to handle (if tame), - and mine do respect their electric fence, but it is mains powered - good meat, sell lambs as lightweights, easy births, usually twins and good mothers. The fleece is very good, lots of colours available, although I only keep white ones. They will do well on rough grazing. Also the bigger ones (go for commercial Shetlands) can be readily crossbred, and for example cross txl lambs make fat lambs with not much additional feeding in good time. But before you get any - read the book(s) on sheep and go to a lambing course, preferably longer than the usual one-day courses offered.
