We have met a family here who raise all sorts of animals, including these "hair sheep." On the most miserable, cold day of the year (I say that all the time) we visited the new lambs. The family is very lucky to have a huge indoor shop/barn, and the animals can live in there when it gets too cold. These sheep are pretty hardy, and they are raised for their meat, since the wool sheds naturally and isn't very valuable.
One of the highlights of visiting is the indoor rope swing. Fights usually break out on who gets to take a turn.
