This is what I saw:
You will note that the Yahoo Weather chart seems to taunt me, showing the actual temperature at - 39C (roughly -38F) and tries to lighten it by saying it feels like only -38C!
Later in the day it got warm enough to let some of the more woolly ewes with bigger lambs outside, this being Diamond, Blackie, and Patsy. Everyone else stayed in the barn (boring, but slightly warmer). Of course they all got extra meals throughout the day.
I think they blame me for the bad weather, and refused to look at the camera for their picture to be taken.
A sheep keeper, especially when there are lambs, must be aware of the temperatures for the week ahead, and be willing to plan accordingly. The ewes who are not doing as well should be kept in and fed extra, any with small lambs, young lambs, or even triplets, should be kept in, as should those who do not keep their lambs close. Any ewes who are due to lamb should certainly be kept indoors in climate extremes.
