It's my first winter with my flock. It's been below zero farenheit for weeks, with the average being -10. We have a metal waterer with a heating element in the tank. The part the chickens drink out of freezes solid and I have to keep going out there to unfreeze it during the day. It's a pain since I also have 2 young toddlers. Anyway, what's the best setup? Should I get one of those base/underneath the water heaters? Or am I just out of luck and it's too cold?
