Need a little help. Is this molting, picking, mites, or an over agressive rooster? Thanks!

In case it matters, I've got 1 rooster & 9 hens.

Are those new baby feathers or remains of the old feathers?

that honestly looks like mites you usually can see the eggs on the skin eek! But maybe I am wrong.

I'm not sure. How long does it take new feathers to grow? The white rock has looked this way for over a few months now. I initially thought moulting, but the longer it's gone on I'm not sure. I've got 1-2 other hens that are missing the same or less feathers as Golden comet in the pic. The white rock just looks way worse than them. All the other girls look fine. No feathers missing at all.

I had the same problem with just one hen, but I actually caught another of the hens pecking at her feathers. In my case, I think it was because they were locked up for the winter in their coop, after having been free range before that. They were bored. It took about 3 weeks separated from the others in the chicken hospital (my garage) for her feathers to come back enough where I thought she could withstand the cold temps and go back with the others.

If you can pick up these hens and check them for mites, I'd say that's a good starting point. You can either rule them out as a possibility, or treat those affected.
