Help is something wrong with my chickens?!

[Crazy4Fowl]

I have noticed in the past few days (maybe like 8 days) my chickens have been getting spots on their comb and wattle. (the red thing on the top of their head and the red thing below their head.) The spots have been getting bigger and expanding outward. I don't know whats wrong but its on all the chickens. Is it normal?
Here's a picture of my barred rock, Blanca before she had them.... don't judge her name I know she isn't all white...

Before:

Today (I just took this photo like 10 minutes ago):

From the second photo of Blanca it looks like it could be fowlpox https://www.backyardchickens.com/a/avian-pox-how-to-treat-your-chickens-for-avian-pox

Ok thanks so much @Ol Grey Mare ! You're right it does look like that, but for the black austrolop it doesn't look like that does it?

Definitely fowlpox. My flock contacted dry fowlpox this summer, likely from Mosquitos. It's taken about 4 months to clear out.
