We had -37F here last night (air temp, wind chill was -54F)...which was mighty cold.
My birds are all OK. I am worried about roo with possible frostbite on comb, but I have 3 heat lamps on in their coop (which is insulated pretty well).
We get lots of cold and snow here (Northwest Chicagoland in snow belt), and we built the coop knowing temps get down below zero. My main concern is keeping it above 32 so the water doesn't freeze (I am dealing with frozen pipes in my house tonight, as the temps are way down again to -25F with -40F wind chill).
But yes, the birds will freeze to death like anything else. If it gets below 20F, i would keep some sort of heat available. I personally think it is uncomfortable at those temps, and chickens will be chickens and wedge themselves in somewhere...
