I'm about to buy a bunch of water cups for my chickens and sell or reuse all the 1gal waterers as scoops or something. I'm just sick of them. Anyway, I need to know how to keep them from freezing. I was going to get an aquarium heater and toss one in the bucket, wrap the pipes in foam insulation. Wrap the insulation with ductape so the chickens won't eat it. We all know they love styrofoam, so I'm sure the other stuff they will mess with too. They will be in the coop, not insulated, chicken door open, 2.5x3ft window always open and a 1.5x3ft window also always open. Do you think this will be enough? Anything else I can do?
