Water in the Winter?

Here are a couple of pictures of what sheep like to do in the winter for their water needs. Even while they're given access to open or free running water, the ewes prefer to eat snow. They just munch along eating clean snow in front of them. Of course, this wouldn't work if it was in a trampled down bedding area, but it gives you an idea of the adaptability of farm animals and wildlife.
Here we see Wild Rose Farm Dorset ewe #114 enjoying fresh snow on a cold & sunny day!
