I've been reading and reading about freezing temps and keeping water thawed. I fought it and fought it but the only thing I could really come up with is keeping the Coop up to temp. I live in North Pole Alaska (yes there is a real North Pole) and our winter time temps seldom ever get above 0 usually an average temp of -5 (yes thats below zero). I have to run 2 heat lamps in my super insulated coop. The coldest its been this year is -35 and the water stayed thawed. The lights keep the coop temp about 40 above. My questions are this: Will running a light 24/7 start to effect the chickens? So far production has been normal. What is too cold for the chickens? Thanks For the help.
