Does anyone know what this is caused from?

[DimondaleBergs]

I sure hope someone can help me with this. About two days ago I noticed that one of my hens looked a little rough around her behind. The pictures below are from two days ago...today, she looks a little worse....I didn't get pictures today though.
Can someone tell me what this is from? And what I should do (if anything) to help her? We have no roo's and she's eating and laying fine.
Thanks

Is she 17 months old? How long has it been since you've dusted the birds?

Fred,
No she's not quite 7 months old. I haven't dusted them....didn't know I needed to....this is my first flock of chickens

Looks like it could be mites and/or lice, I would dust them with 5% Sevin dust or poultry dust... You'll also nee to treat their coop/perches/nesting boxes.

Note: Do not waste your money on DE, it won't work, I know, I tried!

Thanks, Kathy
I will go get some today! I'm going to change their bedding this week also. Do I just sprinkle it on the girls? LOL I've dusted my garden before, but never living creatures! lol
Oh...and I haven't noticed any of the others with the issue, but I will dust them just the same. LOL I'm always seeing them in their little dust bowls that they dig in the run...lol

Last weekend I dusted the girls with powder I found for mites at Family Farm and Home. They didn't have any of the DE 5%. I also changed all the bedding in their next boxes, the shavings on the floor of the coop, and even sprinkled some in the run. Do I need to repeat this? And if so..how often? I also have noticed that some of the girls have feathers missing from their bellies. How do I know if this is working? I don't want my girls naked for winter! lol
Thanks
