Humidity /Temperature fluctuations are damaging on a sliding scale. The more humidity that is in the air...like a rainy day. Just 30 degrees has potential to frostbite skin. So actually this rainy weather and then a wet bird put away in a coop with temps falling fast is actually not a great scenario. Luckily for us that is just a short time of year. And up here in Northern Minnesota we generally have a dry cold. So it depends on Relative humidity outside on whether you'll get frostbites. I also am a firm believer that extended periods of below zero weather is hard on combs and wattles. Cold is cold. So that's why I do have a supplemental flat panel heater for those long stretches. Last winter wasn't so bad ...but the two winters before were very very cold and long. 6 solid months in the coop and run and hardly a week's worth of days started above zero. Mostly -20's if I recall to start the day. woooook. Gives me the shivers just to think of it.
roosters usually get the most damage. Hens will tuck their heads under their wings on those really cold nights.
Ya. It hurts them. They are sensitive there. They just dont express pain because they are prey animals. Frozen combs and wattles can be messy business. Get infected and potentiall kill a bird. Just the swelling in the wattles from the freezing can inhibit them from eating and drinking. No good. I've dealt with it on our Single Comb New Hampshire.
That was a fun first winter. Not.
Nathan: they do. Broken toes or feet are susceptible...So lower the roosts. Feet with bad bumble foot. Swollen and comprimised blood circulation. Feet that are in wet soupy messes all the time. Feet that do not have good wide roosts to wrap feathers around to rewarm.

So your not the cause of the funeral parlor going up into a blubbery hot fire.
Minnie: sorry about the insurance hassle. Is it progressive? They offer lower rates but our Auto Body guy says they haggle over every little plastic bolt or screw.
