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.

Have you been spraying them? If you have treated them in 7 days intervals with something like Permethrin, then I would treat them any more unless you see bugs.

Feather loss can be from number of things. You have a rooster, so mating will naturally wear off feathers in time.
I didn't say that you have a broody hen - the loss looks like a broody patch. It's not uncommon for hens to pluck feathers from that area. I don't really see any irritated skin, it's nice and smooth just like a broody patch.

It was permethrin 10. I mixed according to the directions and did them twice 7 days apart and the coop and the ground in the run.

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

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

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

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.

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.
