Overview
If your chicken is not moulting properly, the first things to check are whether the feather loss is normal for the season, whether the bird looks generally well, and whether there are signs of parasites, poor nutrition, stress or pecking from other birds. Moult can vary a lot between chickens, so a slower or patchier moult does not always mean something is wrong.
Things To Check
1. Check whether the feather loss is happening in the usual moult season or after a change in weather, light levels or laying pattern.
2. Look closely for redness, broken skin, scabs, swelling, discharge or areas that seem sore or hot.
3. Check for mites, lice or signs of irritation around the vent, under the wings and along the neck and back.
4. Watch whether other birds are pecking at the chicken or pulling out feathers.
5. Review what the bird is eating and drinking, and whether it has had a dip in appetite, weight or energy.
6. Check the coop for damp bedding, poor ventilation, overcrowding or anything that might be causing ongoing stress.
7. Notice whether the bird is still behaving normally, perching, dust bathing and moving around as usual.
Common Causes
The most common reason is simply that the bird is moulting more slowly or unevenly than expected. Some chickens drop feathers in stages, and the timing can vary from bird to bird.
Parasites such as lice or mites can also make feather loss look messy or incomplete, especially if the bird is itchy or restless.
Poor nutrition, low body condition, breeding stress, changes in daylight, flock bullying and general environmental stress can all affect how a moult progresses.
Less commonly, feather loss can be linked with skin irritation, pecking injuries or another underlying health issue.
What To Do
Keep a close eye on the bird for a few days and note whether the pattern is changing. A simple photo log can help you see if things are improving or getting worse.
Make sure fresh water is always available and that the bird has a suitable balanced diet for its age and stage.
Keep the coop clean, dry and well ventilated, and reduce any obvious stress from overcrowding, bullying or abrupt changes to routine.
If you spot lice, mites or skin damage, deal with the environment and flock management promptly, and keep monitoring the bird closely.
