Guess I'll be getting handy and building a new winter watererAmynrichie, I'd love to hear how it goes without the pump - am thinking that I'll try first without and add it later if needed.
Our Midwest temps have been down to 0 this week, and so far no freezing. There is frost above the water line, but the horizontal nipples have not frozen. I keep my bucket in the coop out of the wind.
