freezing wattles and combs

[Member 441608]

Where I live it is getting pretty cold. (Below freezing)
About what temperature should I put something on my chicken's combs and wattles?
If I need to be doing so; does anyone have any tips on how to catch a rooster to put the petroleum jelly on his comb and wattle?
Thanks.

I haven't kept chickens in the severe cold yet, but putting Vaseline on combs and wattles is supposed to help keep them from getting frostbit.

I don't put anything on my chicken combs, since I don't feel that it prevents it. However, I have seen frostbite occur when temps are below 15 degrees F, and anytime they get feet or wattles wet during freezing temperatures, it can happen. Freezing temps plus high humidity causes frostbite. Increasing overhead air circulation and adding dry pine shavings to keep bedding dry can help. Here is a good link or two to read:
