Despite my best efforts with this last cold snap my chickens with the bigger combs have some frostbite( lows of -22, highs of -6.) Do I need to do anything? I have been putting vaseline on. should I switch to polysporin to prevent infections? Will it heal on it's own?
Yes, I would switch to an antibiotic because they can easily get a secondary infection. Just be sure whatever you use doesn't have a "caine" drug like benzocaine, cetacaine, etc.
