Avian Pox??

[6ChicksandaDog]

Hello I need some help one of my chicken started getting something black on her comb, I looked it up and I was thinking it could either be frostbite or Chicken Pox? Please help! Also she is one of my girls that is molting could this have anything to do with that as well??

These are the best pictures I could get of her

Thank you so much for your help.

I had a similar concern. My understanding is that the pox can come and go without too much damage. If dry pox is what my girls had, it did just come and go. They might also be scabs from pecking.
