Hey, Guys! Just yesterday, we got our first snow, and it's one of the earliest snows we've had in a while. The temperature is currently in the '20s/30s and dropping. This is only my second year of raising chickens and last year we didn't have a cold winter. I'm not sure if I should put a heater in the coop or if there are other way's you could cold-proof the coop. Any ideas would be greatly appreciated . Thanks, Guys!
