Overview
If your chicken is losing feathers, the first thing to check is whether this looks like normal moulting, feather pecking, parasites, or skin irritation. Feather loss is fairly common, and many cases are linked to the flock, the coop, or the time of year rather than a serious problem.
Things To Check
1. Check whether the feather loss is happening all over the body or in one area such as the neck, back, vent, chest or tail.
2. Look closely at the skin for redness, broken skin, scabs, bare patches, swelling, or signs of irritation.
3. Check for mites or lice around the base of the feathers, under the wings and near the vent, especially in the evening.
4. Watch the flock to see whether another bird is pecking, bullying or pulling feathers from the affected chicken.
5. Consider whether the bird is moulting, which often causes a more even pattern of feather loss and new pin feathers.
6. Check the coop for damp bedding, overcrowding, poor ventilation or dirty areas that could be irritating the skin or encouraging parasites.
7. Notice whether the bird is otherwise eating, active and behaving normally, or whether it seems dull, tucked up or uncomfortable.
Common Causes
One of the most common reasons is moulting. During this time, chickens shed old feathers and grow new ones, which can look dramatic but is often normal.
Feather pecking from other birds is also common, especially if the flock is stressed, crowded, bored or unsettled.
External parasites such as lice or mites can cause itching, damage feathers and leave the skin looking irritated.
Less commonly, feather loss can be linked to skin irritation, poor nutrition, repeated rubbing, or another underlying health issue.
What To Do
Start by separating normal moulting from patchy loss caused by pecking or skin irritation. Keep a close eye on the pattern of feather loss over a few days and make notes if it changes.
Check the coop and bedding, and improve cleanliness, dryness and ventilation where needed. Make sure the flock has enough space, enrichment and access to food and water so stress is kept as low as possible.
If another bird is pecking feathers, reduce triggers where you can and monitor the group closely. If you suspect parasites, check the bird and the housing carefully and keep your routine cleaning thorough.
Feed a balanced diet and make sure the bird is not being left out by others at feeding time. If the skin looks sore, the feather loss is spreading, or the chicken seems unwell, speak to a vet.
Products That May Help
Good coop hygiene and routine smallholding care can be useful when you're checking for causes of feather loss, especially if you're looking at bedding, housing and flock cleanliness.
