Hi Johnny and all. I live in Duluth MN. Not quite as cold, but close. Lake Superior can bring some winds and cold. I overwintered 40 chickens last year, some in an attached garage where temps were always above zero F, ventilation was my problem there, build up of amonia smell. I also had two coops 4'x8'x5'high on trailers, unisulated with 6" of pine shavings. The birds chose where to go, probably the lowest in the pecking order stayed outside, the roost in the attached garage coop only allowed for 20 birds or so. The only time the true outside birds ever had problems was when temps got into the 10 - 20 degree below zero range, and only three birds got frostbite comb. We only get a few 30 to 40 below days, maybe a week or two of 10 - 20 below.
Hows that go, IMHO (in my humble opinion), I would be leary of heating the coop all the time, I am going to heat the outdoor coops when temps are below zero. The chickens do lay in the garage coop with temps always above zero, I had no problems with frozen eggs. The birds really do get by fine in the cold, just not below zero in my experience. Ventilation is easy to keep track of, you have plenty of options to open or close as needed, usually if I opened the human door to the garage coop during the day, it aired out just fine. Loose heat, gain ventilation! That is the trade off. I had no problem with ventilation in the outdoor coops with 7-10 birds in each of the outdoor coops, though I open the chicken door daily for them so there was no retaining of heat and no problem with build up of amonia. I will heat only at night anyway, the sun on cold days usually heats the inside of the coop with one 2'x2' window.
