Red, bare bottoms

[nekocafe]

Hello! My friend has 8 chickens and 5 of them have red, bare backsides and bottoms. Could this be from bullying? And is there a way to treat it or prevent it from continuing? A couple have regrown feathers and some others are trying too but some are still very red and featherless. Photos posted for reference. Thanks in advance!

When was the last time they were de-wormed? And how does their poop look?

From what I’ve seen the poop looks normal. No dewormer, they haven’t been treated for anything from what I know.

I would put some apple cider vinegar in their water, start watching them very close for a feather picker, check them for mites and lice, and make sure that they have an area to dust off. Then let me know what you find.

Thanks! These are my friends chickens so I’ll let her know about the ACV. That’s what I put in my chicken’s water too. She also said she didn’t see any mites or lice so must be some pecking going on.

Apple cider vinegar wont do anything for bald butts, neither will worming with an authentic wormer. It's not feather picking nor external parasites.

The bald butts are due to urates in feces scalding their rear ends causing redness, swelling and irritation. It's been going on for awhile judging by the photos.
Treatment is Nu-stock which can be found in the Equine section at a feed store.
Shake the tube well and apply the Nu-Stock on the affected areas, wear disposable gloves when applying it. The area will heal, feathers and fluff will regrow in time.
IF there's feather picking, it wont happen again once a hen gets a mouthful of the Nu-Stock.

Can I see a picture of their poop? I tend to think feather picking considering a couple of them are fine.
