I tried the vaseline thing, then bag balm on mine, and I honestly think it is what made things worse. If you look at the photos I attached of my hen's comb, it looks really bad, and that was after trying to be proactive with the salve. The black you see on the comb in my photo is not frostbitten tissue..it is actually dirt collecting on the vaseline/bagbalm. The white part is the damaged tissue. I stopped using the salves, and the frostbite never got worse. The wattles..well...I think THAT was caused by me giving them warm mash in the mornings, and the steam coming off the food. I also don't do that anymore. I haven't used anything this year, and they seem to be fine.
