So I only have two chickens at the moment and need some ideas. I live in Colorado, and it gets collllddddd. Their water is always frozen and I'm constantly having to change it so they can get some. I know they sell the big three gallon heated waterers, but I only have two birds and that thing wouldn't even fit in their coop. So I was wondering if anyone has taken on the challenge of creating their own heated waterers. I had thought about those tank heaters they have for fish tanks, but it doesn't seem quite right. Any other ideas??
