In the warmer/sunnier months I keep the chickens' water out of the coop, but winter is proving a whole new ball game. Not only does it freeze almost instantly (I'm in Maine), but the girls are on artificial lighting meaning their light turns on at 2 and I'm not up until 6. That means zero water for four hours unless I have water in the coop. I've been keeping water in the coop, but it's bringing the humidity up. What do you all do? I don't mind the freezing issue, but I worry about the four hours without water. Thoughts?
