Overview
If feather pecking seems worse at night or in the coop, the problem is often linked to the housing rather than the birds being settled. Common reasons include crowding, poor lighting, boredom, stress, damp or dirty bedding, or a hidden irritant such as mites. It’s sensible to check the coop closely, because night-time pecking can be easy to miss during the day.
Things To Check
1. Check whether pecking happens after the birds go into the coop, before they settle, or first thing in the morning.
2. Look for bald patches, broken feathers, redness, scabs or bleeding around the neck, vent, back and tail.
3. Check the coop for overcrowding, blocked perches, poor airflow or signs that birds cannot keep their distance.
4. Look under perches, in corners and around bedding for signs of mites, droppings build-up or damp areas.
5. Check whether the coop lighting is very bright, uneven or left on too long, as this can keep birds active.
6. Think about whether the flock has enough space, enrichment and access to feed and water during the day.
7. Notice whether one bird is always the target, or whether several birds are involved.
Common Causes
The most common cause is flock tension in a confined space. When chickens are tucked up in the coop, they can’t move away as easily, so pecking may become more obvious.
Lighting is another common factor. Too much light, sudden light changes or an unsettled bedtime routine can keep birds restless and more likely to peck.
Boredom and lack of enrichment can also play a part, especially if birds spend a lot of time in the coop or run with little to do.
Dirty, damp or cramped housing may contribute by making birds uncomfortable and more irritable.
Less commonly, feather pecking may be linked to parasites such as mites, skin irritation, or a bird that is unwell, stressed or being bullied within the flock.
What To Do
Start by checking the coop at the time the pecking seems worst. Watch which birds are involved, how often it happens and whether one bird is being singled out.
Improve the basics first. Give the house a proper clean, replace damp bedding, check ventilation and make sure there’s enough space for the number of birds you keep.
Keep lighting calm and consistent. Sudden changes, very bright bulbs or long evenings of light can make birds more restless.
Provide extra interest during the day, such as scattered feed or other suitable flock enrichment, so the birds are less likely to focus on each other.
If one bird is getting pecked repeatedly, separate the birds if needed so the damaged bird can rest and recover without further stress.
Keep monitoring for changes over the next few days. If the pecking is spreading, skin is being damaged, or the flock seems generally unwell, get veterinary advice.
