I see people referring to the ambient temperature a lot, but not necessarily the temp inside the coop. Our coop is not insulated. It is raised up off the ground and we've enclosed the space under the coop with straw. We've also placed several bales inside the run, to give them some wind breaks. Good ventilation, no drafts. The thermostat inside the coop is usually within a few degrees of the ambient temperature. I've heard people say that their coops will stay around 40 due to the body temperature from the chickens, not my girls. The temperature probe is right near their roost and it's consistently within 5'ish degrees of the outside temperature.
A couple of my girls have small spots of frost bite on combs already. Prior to this week, it's been low single-digits. We did start using a oil heater, which usually keeps it 10-12 degrees above the ambient temperature. The frost bite happened even with the heater running.
Actual temperatures will be below zero with wind chills much colder. That means the inside temperature of the coop will probably be under 10 degrees. I've very concerned. Two of my girls decided to go through a partial molt late December and are just now starting to feather out (just around their neck, they didn't molt anywhere else).
Do I add more heat?
As far as thermal shock goes, the reality is that in KS, the temperature can swing 30-40 degrees within just a few hours. If we kept the coop at 15 degrees and the power went out, it would honestly mimic what our stupid weather does on its own. Additionally, if their power went out, it would be out in our house too. We could go attach a small generator within minutes.
Are they really okay just hanging out in sub-zero temperatures? I get the down coat argument, but I have a down coat, I'm much larger and I wouldn't be safe in sub-zero temperatures.
