I have been reading everyone's ideas about keeping water from freezing. I also do not have electricity in my coop. Sometime next summer we are going to dig a trench and put in electricity but I have one more winter to go through. Last summer we had 23 chickens. I used the red and white waterers from TSC that hold a gallon or so. I have two of them. One stays in our tub in the house and one outside. In the morning the inside one goes out and the outside one comes back in to thaw. Then, in the evening we do it again. BUT, I have 4 kids so they have to take turns doing it. We need to go outside twice a day to collect eggs, check on things, and take care of rabbits anyway. The only really bad time was when the temp was WELL below zero and the drifts were a@@ deep and the wind was hurricane strength. Then it was only me and the oldest suiting up to do it. It sucks but right now it is the only choice I can think of. I wish there was a way to heat the water with solar or a battery. I just keep thinking if the chickens have to live out there in the cold the least I can do is visit twice a day and take of their needs. Right?
