Animals need sunshine as well. In fact, I can guarantee you that my eggs and chicken contains a lot of it. Happy, healthy animals deserve the sunshine. It was -20C this morning and the chicken's were NOT happy. As soon as the sun shone on the coop I opened the door and threw out the hay. They loved it.
We also bundled ourselves up and soaked up the sun...Nothing like a little Vitamin D to get rid of the winter blahs.
