Still no idea what’s going on with my hens comb and growing black spots

[Ohsrsly]

My pullet (about 7 months old) has these black spots on her comb and wattles. They started as small spots a few months ago and just keep growing. She acts normally otherwise (that is she eats, drinks, runs around with the others, and lays eggs). She does not have signs of mites or lice. None of her flock mates has anything remotely like this. It has been at least a few months since these started as smaller spots and just keep growing. I’m stumped!

Fowl pox? @Eggcessive

I wondered about that but wasn’t sure since none of the others have any spots— is that normal for just one to get it?

Sorry, I know nothing about FP yet, that's why I tagged some Educators. I hope to learn, though.

Looks like it could be fowl pox/dry pox, A virus spread most likely by mosquitos. I would expect others to be infected. However, since there are no other symptoms like weight loss, lethargy, respiratory issues or diminished egg production - I would consider something else.
In the absence of other symptoms, I would look at the possibility of abrasions. Whether fighting/biting or catching comb and wattles on something in the environment.

How many months has she had this? If she has had this for months, I would think they were pecking injuries rather than fowl pox virus. Fowl pox usually causes a series of lesions to show up as a beige spot that turns to a brown scab, and lasts around 3 weeks. Some outbreaks could be more severe. Here are some links to read with pictures of fowl pox:

They started as smaller beige spots that darkened and grew, but it has definitely been more than three weeks. Here is what they looked like about three weeks ago. @Eggcessive
