Perpetual Dirty Butt

[Airwaves35]

I have two ~9 month old White Bresse hens I keep in a chicken tractor and let range during the day. One I have never had a problem with, and one has had a perpetually soiled vent. She has never seemed sick; she runs around, flies up to roost, hangs with the other hen, etc. although I don't think she laid very often. Since the other one was fine I didn't bother trying to address it too much other than trying Corid for a little while.

Any ideas or suggestions? Thanks.

Possibly Coccidiosis. I had to put a chicken down because of it. Check it out online. Best of luck !

OP already mentioned treating with Corid, and a bird with coccidiosis overload wouldn't likely survive for long term soiling to be an issue.

I had one of my girls with the same problem. In the end I cut the fluffy butt feathers and washed her.
She was fine apart from the mucky butt so I left her.
She’s fine now and her poops are normal.
Perhaps a dodgy curry
