Why does my chicken have feather damage around the neck and under the wings?

Overview
Feather damage around the neck and under the wings in chickens is often caused by lice, but it can also happen with pecking, rubbing, moulting or other skin irritation. Lice are a common reason to check first because they often affect feathered, warm, hard-to-see areas like the neck, under the wings and around the vent.
You may be able to spot the problem yourself by parting the feathers and looking for eggs attached to feather shafts, tiny moving insects, broken feathers, scabs or irritated skin. A proper check of the bird and the coop usually gives you a better idea of what is going on.
Things To Check
1. Part the feathers around the neck, under both wings and near the vent to look for lice, eggs, broken quills or irritated skin.
2. Check whether the bird is scratching, preening more than usual, shaking, or looking restless, especially in the evening.
3. Look for feather loss that is patchy rather than even, which can point towards rubbing, pecking or parasite irritation.
4. Inspect the skin for redness, scabs, soreness, dampness or areas where feathers look chewed or frayed.
5. Check other birds in the flock, because lice and pecking issues can affect more than one chicken.
6. Look at the coop, perches and nesting areas for signs of poor hygiene, debris build-up or birds crowding together.
7. Notice whether the problem started after moulting, a change in housing, new birds joining the flock, or a period of wet weather.
Common Causes
Lice are one of the most common causes. They live on the bird and can lead to broken feathers, irritation and feather loss in areas that are easy for them to reach.
Feather pecking from other birds is another common cause, especially if the flock is stressed, overcrowded or short of space.
Moulting can also leave feathers looking untidy or sparse, and it can be easy to mistake for parasites if you’re not looking closely at the skin.
Less commonly, feather damage can be linked to rubbing on housing, poor perch design, skin irritation or other external parasites.
What To Do
Start by checking the bird carefully in good light, then look at the rest of the flock and the coop so you can see whether the problem is isolated or shared.
Improve routine coop hygiene and remove damp bedding, droppings and built-up debris, as this can help support a cleaner environment for the flock.
If more than one bird is affected, it makes sense to check them all rather than focusing only on the most obviously affected chicken.
Try to reduce stress factors such as overcrowding, limited feeder space or cramped perches, since these can contribute to pecking and feather damage.
Keep an eye on whether the feather loss is spreading, whether the skin looks sore, or whether the bird seems unwell, and note any changes over a few days.
When To Contact A Vet
Speak to your vet if the skin looks badly inflamed, there are open sores, the bird seems unwell, or the feather damage is getting worse despite good flock management. A vet can help check whether parasites, infection or another skin problem is involved.
