Quote: IMO it's best not to even touch it......it's compromised tissue and touching it could very easily make it worse.
Had several birds with frostbit combs and wattles last winter, most were the mild graying of the tissue, some had black necrosis that eventually soughed off. I think the wattles get bit because they drag them thru the snow.
I just keep a watch for swelling that lasts more than a few days or obvious infection.
Woody's wattles were swollen for 2-3 days, then swelling receded and tissue turned black, took a couple months before black tissue came off and pencil thin scars developed, by spring you could hardly tell it had happened.
The more ventilation the better..barring strong drafts on roost area.....but Michigan is humid, nothing can reduce that other than full on HVAC.
