my california white has a bleeding comb and it is swollen. I can't tell for sure where the blood is coming from, but it is also swollen. It was about 15 degrees in the coop, but well below 0 outside with the wind chill. Could this be frostbite? Does anybody have pictures of a frostbitten comb? None of the others have any problems that I can tell and the coop is warming up to about mid twenties with all doors closed. Is it okay to put her back iin the coop when it is still so cold? Do I keep her inside with me until I figure this out?
