What’s wrong with my chicken?

[Saphie]

I noticed yesterday that my chicken had black spots, and now it is getting worse. Is this fowl pox, are the older chickens attacking or something else?

@Miss Lydia
Would you be able to help? Do you know what’s wrong with my aunt’s chicken?

I am no expert, but it looks like fowl pox, based on other pictures I've seen.

Fowl pox, I had a hen with it recently.

It'll run it's coarse over a few weeks.
It's a virus transmitted by mosquitoe bites.
