My hen has a white spot on her comb

[ArtemisMaeve]

So probably not an emergency but this is my first time raising chickens, I’ve had ducks my entire life but chickens are new to me. My hens comb is flopped over and has a white spot on it, it showed up the other day, I don’t see any other spots on her or my other chickens. It hasn’t changed in size or color or anything either. She doesnt seem to be uncomfortable. She seems healthy in every way. Should I be worried?

Looks like dry fowl pox. Not much to do, but I added some probiotics to their water and gave some fermented feed when mine just went through this.
