Frostbite

[4Bchicks]

I know this is an issue. I live in northern Wisconsin. Day temp is 12-15 degrees the last few days. My flock has been fine till today. Black coloration noted on the top of a couple combs. I did put salve on the comb and waddle this morning. I keep the coop 35 degrees at night when the door is closed. I use a black reptile light bulb for heat at night. Should I not be heating the coop or just leave the door open to increase ventilation. I have a window on the left side of the coop but I have read chickens don't like drafts and it would be just about perch height.
Any help is appreciated...

Sounds like you need ventilation, although the door isn't the best place to provide it. Ideally it should be the high point of the coop. The frostbite was likely caused by humidity in the coop, not really the cold temps.

Maybe these articles, written by a Canadian, will help:

Coop temp 40's, humidity 33%. I have been changing out the litter though. My thermometer is toward the peak of the coop. I only close the door at night. Occasionally find egg cracked open the last few mornings.
Thanks for the articles.
