What’s wrong with these feathers

[Aleta]

I recently noticed that one of my Ameracauna hens has more fluff than feather on some of her feathers on her back as I wonder if I should be concerned. I do have rooster but none of my other hens seem to have this problem. Please help. I will post some pictures. Thanks

How old is she? The fluff is normal and is usually underneath feathers and are visible when the feathers fall out.

Do you have a roo?

We got her in mid March so she is about 7 1/2 months now. She went through a big molt this Summer and started laying eggs in early October. Yes I have a rooster. I was wondering if the rooster mounting her could be causing damage to her feathers. However none of the other hens have this.

There's likely the answer to your question.
She may be more submissive than the others.
How old is the "rooster" is he 7 1/2 months too? Young cockerel filled with hormones.
I would just watch the area, likely she will be bald pretty quick, it bothers us more than them, but some folks will put saddles on the overmated ladies. I have done that too.
Now I usually just keep cockerels separate and put them with the girls when they are all more mature.
