After the unseasonable warm temperatures we have experienced this winter, things have returned to normal. Well kind of…
While the Caldwell pasture is four inches deep in snow, the Parma pasture is bare and dry. We have had a succession of wind, graupel, and sunshine. It has been hard to know what the weather will be in the next hour. The moveable shelter has done the sheep well. When the graupel falls, the sheep hide under the shelter. When the sun comes out the sheep return to grazing or playing, and the graupel melts away. When the wind blows they hardly care.
Witness if you will, a 14mph (22kph) wind with warm sun. All the sheep, under the shelter chewing cud without a care in the world.
Sunday afternoon, the wind was reaching well over 20 mph (32kph). The shelter was whipping about. We were not expecting the clouds to break, but we were also not expecting any precipitation til Monday morning. The shelter is moved on Sunday evening anyway, so it would be down for only a couple extra hours. After all, we needed to put a few additional grommets in it anyway. The decision was made to take the cover off and do some work on it.
After the work, when we came back out to move the shelter, we were met with an interesting sight. 
All but one of the sheep were loafing under the shelter that was not there. We know that sheep have excellent understanding of spacial relations, and rudimentary math skills, but could they really believe that the shelter exists in a quantum state?
I think they are just messing with us.
