Sokol,
What we did for years when was we kept 3-4 breeding ewes who lambed each year, but then we would get 3-4 orphan lambs as well. The boy lambs all were castrated every year and went- either to market for meat and we would get a couple slaughtered for us and put in the freezer. The females, depending on how many there were and how nice they were, we might keep to join the flock, or also send to market. We were once given a pure texel orphan ewe lamb and her brother, and we kept her and bred from her every year. When we sold all the sheep eventually, she went as a breeding ewe and we got quite a lot of money for her..... Not bad for a free lamb!
