Hi! Living way up here, it always gets really cold in the winter. In fact, yesterday the chicken's waterer officially froze over completely, which is a problem because, obviously, they need to get to their water and if it's frozen, they can't.
What can I do to prevent the water from freezing, besides buying an expensive heated waterer that I've seen some people have?
Thanks!
