Why do my chickens keep preening and pecking at their feathers?

Overview
Chickens preening and pecking at their feathers is often normal grooming, but if it’s happening a lot it can also point to lice, feather irritation, dry skin, feather damage or flock stress. The main thing is to check the bird and the coop carefully, because the cause isn’t always obvious at first glance.
Things To Check
1. Watch when the behaviour happens. A little preening during the day is normal, but repeated pecking, fussing or scratching may be more of a problem.
2. Part the feathers and look closely at the skin, especially around the vent, under the wings and along the neck.
3. Check for lice signs such as tiny moving insects, nits attached to feather shafts, or birds that seem restless and itchy.
4. Look for feather loss, broken feathers, scabs, redness or irritated skin, especially if the bird is pecking the same area repeatedly.
5. Check the coop, perches and nest boxes for dirt, damp bedding, dust build-up or signs of other parasites such as red mite.
6. Notice whether one bird is being pecked by others, or whether the whole flock seems more restless than usual.
7. Check for changes in feed, weather, moulting or recent stress, as these can all affect feather condition and grooming behaviour.
Common Causes
Lice are a common cause of excessive preening and feather pecking. They can make birds itchy and uncomfortable, and you may see them more easily under the wings or around the vent.
Moulting is another common reason. New feather growth can make chickens preen more than usual, and some pecking can be part of normal feather care.
Dry skin, dirty feathers or irritation from damp, dusty or crowded housing can also lead to more scratching and preening.
Feather pecking from other birds can cause a chicken to keep pecking at its own feathers or the damaged areas. Stress, boredom and tight space can contribute to this.
Less commonly, another parasite, skin issue or health problem may be involved, especially if the bird seems unwell, is losing condition or the problem is affecting several birds.
What To Do
Start by separating normal grooming from repeated, restless preening. If the bird is otherwise bright, eating and behaving normally, keep a close eye on it for a few days.
Check the flock and the housing thoroughly, then clean and refresh bedding if needed. Good coop hygiene can make it easier to spot parasites and reduce irritation from dirt and damp.
If you suspect lice, check every bird in the group, not just the one that looks most uncomfortable, because parasites can spread within the flock.
Make sure birds have enough space, enrichment and access to dust bathing, as boredom and crowding can increase feather pecking.
If feathers are broken or skin looks sore, avoid handling the area more than necessary and monitor closely for any worsening changes.
When To Contact A Vet
Speak to your vet if the bird has bald patches, bleeding skin, heavy feather loss, seems unwell, stops eating, or if several birds in the flock are affected. It’s also sensible to get advice if you suspect lice but can’t bring the problem under control with normal flock management.
Products That May Help
Keeping poultry housing and routine cleaning in good order can help support day-to-day flock management when you’re checking for lice, feather damage or general irritation.
