We have plenty of shelter but sheep are just not as concerned with weather as goats tend to be. We've also found that if they can keep their heads buried down in a round bale as they eat they don't seem to worry about how wet the rest of their body is getting. So they have been wandering around eating as usual, seemingly unaware of how they look right now. Pretty Girl, one of the Angora goats, has also been out in the weather and was letting me know by the look on her face how distressed she was. It was, of course, her choice to go wander around in the weather in spite of all the nice shelter we provide.
