What’s your humidity like? We have great coop ventilation, but that didn’t seem to help during this cold snap. It was a very humid storm, with freezing fog during part of it. Later in the weather pattern, the humidity at night was about 85%. I’ve seen a lot of discussion about humidity and frostbite in chickens. I guess that the thought is that high humidity in the coop during freezing conditions will lead to condensation on the skin of the comb and increase the chance of external ice forming on the surface of the comb? I’ve been a little hazy on that explanation since I would think that if comb blood circulation was too poor to keep the comb tissues above freezing, then a thin layer of ice wouldn’t make much difference to tissue damage...Nope, he is not a wing tucker. My understanding is that good ventilation is the key and I am sure that my coop having low humidity does help.
