Bald spots on everyone but one

[hilltopchicks77]

Hey! I was worried my chickens have mites .4/5 have bald spots, including the rooster. 1 hen does not. I’ve treated twice (coop and chickens) with peremethin 10. They have plenty of space etc but I’m wondering now if she’s feather picking? Would that maybe explain why she’s fine and everyone else had bald spots? I included photos of her vent area (the not bald one) in case anyone sees something I don’t and can help me figure out what to treat with.

What do the others look like?
How much space do you have?

Is that blood in the first picture? In the upper right?

The other have red/bald spots. I haven’t found anything crawling on them. In fact she has the worst vent area minus the bald spots.

It’s actually paint she walked under a new coop I was building

And I forgot the first part they have a 20x10 run and 6x8 coop with double roosting bars. Only 5 chickens in there (1 roost 4 hens). We have been building a new coop and run next to this one and we have chicks in a third pen. Not sure if stress is causing her to pick everyone. She’s def top of the hen pecking order.

What?

What?

The other chickens have bald/red spots on them. This is the only one that doesn’t. I can’t see anything crawling on any of them. She has the dirtiest vent of anyone which I know can sometimes be a mite symptom so I took photos of hers.

Then post some photos of the ones you are concerned about.

I don't see anything concerning about the photos you posted.

I couldn’t catch them earlier. Our rooster is getting super aggressive lately. I found this from a couple weeks ago. First picture is her chest (I thought where the rooster was pushing her into the ground).

One hen has the same head issue but nothing else
One is bald on her chest but nothing else
The roost has spots on his outer thighs and just under his tail. They all look the same.
