When should I call a vet for feather loss in chickens?

Overview
Call a vet if the feather loss is sudden, spreading quickly, leaving bare skin sore or broken, or if your chicken seems unwell as well as losing feathers. In many cases, feather loss is linked to moulting, pecking, mites or rubbing, but it’s sensible to check the bird and flock carefully before assuming it’s normal.
Things To Check
1. Look at where the feathers are missing. A patch on the back, vent, neck or wings can suggest different causes such as pecking, mating wear, parasites or rubbing.
2. Check the skin underneath for redness, scabs, broken skin, swelling, heat or crusting.
3. Look for signs of parasites, including tiny moving specks, pale debris at the feather base, or irritation around the vent, under the wings and along the neck.
4. Watch the flock for bullying, feather pecking, chasing or repeated mounting, especially if one bird is targeted more than the others.
5. Think about timing. Feather loss during a seasonal moult is often more even and gradual, while sudden changes are more concerning.
6. Check for damp, dirty litter, draughty housing, sharp edges, or anything in the coop that could be rubbing the feathers away.
7. Notice whether your hen is eating, drinking and behaving normally, or whether she seems quiet, fluffed up or off colour.
Common Causes
The most common causes are moulting, feather pecking and external parasites such as mites or lice. Feather loss can also happen from mating wear, rubbing on housing, poor feather condition or repeated preening caused by irritation.
Less commonly, feather loss may be linked to skin infection, nutritional problems or an underlying health issue that makes the bird feel unwell or itchy.
What To Do
Start by keeping a simple note of where the feather loss is, how quickly it’s changing and whether any other birds are affected. Check the coop, litter and perches for rough surfaces, and keep the housing as clean and dry as you reasonably can.
If you suspect pecking, observe the flock closely, make sure there’s enough space, and reduce stress where possible. If parasites seem likely, inspect the bird and the housing carefully and clean the environment thoroughly. If the skin is sore, broken or the bird seems unwell, don’t just monitor it at home.
If the feather loss is mild and the bird is otherwise bright, eating and behaving normally, it may be reasonable to watch for a short period while you check for a likely cause. If it’s getting worse or you’re unsure, get veterinary advice.
When To Contact A Vet
Contact a vet if feather loss is sudden or severe, the skin is red, broken or swollen, there’s discharge or a bad smell, or your chicken seems dull, hunched, off food or losing condition. A vet is also sensible if more than one bird is affected, if parasites keep coming back, or if you can’t find a likely cause after checking the bird and coop.
It’s especially important to get advice if the feather loss is spreading quickly or the bird seems painful, because those signs can point to a problem that needs proper treatment.
