We're in the middle of the polar vortex and it is just miserably cold. The water is freezing over every 2 hours and I've been lugging warm water out to the chickens all day. But they are not drinking! I also thought they would be eating more than usual to stay warm but they seem to actually be eating less. I've offered warm mash (no thanks), warm oatmeal (yum!), warm cooked corn (maybe just a little), scratch (just the black sunflower seeds) and warm cooked pumpkin. They seem basically fine - outside in the (tarped) run and not moving around as much as usual. The've made little nests in the straw in the warmest corner. Why won't they drink??? (And why didn't I buy a heated waterer while the roads were still drivable?!)
