How much comb will he lose?

[SamCO]

All my girls did well during the cold snap but my little cockerel seems to have some frostbite. I’m so bummed. The coop got down to -7 and 45% humidity, while it was -23 and over 85% outside so I felt pretty good about my coop. Anyone with birds with similar frostbite? Think he’ll lose much of his comb? Poor guy. Not sure what to do different next time.
The coop is a 10x12 shed split roughly in half (but the top is open all the way across so airflow is shared. Have a ridge vent, two gable vents, and the large window on the non-coop side stays wide open. This doesn’t meet the 1 sq ft per bird (14 birds) but there was no condensation inside on the windows, and the humidity is so much lower inside, I don’t know how it could stay too much lower with it high outside. No water is kept in the coop. Any advice? Would more ventilation prevent this? I do have a sweeter heater hanging above their roost, but he wasn’t right under it. I feel so terrible. He’s acting totally fine.

He might loose the very tips of his comb. My last rooster had is worse and he lost all the tips. His comb was kinda like a lump on his head how many birds do you have again?

Poor baby

He has no access to mirrors, so just do what you would be a spouse... Tell him he is just as beautiful as the day you met.

The tips lost will not cause long-term suffering.
