Overview
If your chicken is being pecked by flock mates, check the bird for any skin damage, the flock for signs of bullying, and the environment for anything that might be increasing stress or competition. Pecks can be caused by pecking order issues, boredom, overcrowding, feeding disputes or a bird that already looks different to the rest of the group.
Things To Check
1. Check whether the pecking happens at a particular time, such as feed times, after housing, after moving birds, or when the flock is let out.
2. Look closely at the affected chicken for broken skin, bare patches, redness, swelling, discharge, scabs or areas that look sore and damp.
3. Check whether one bird is targeting the same chicken repeatedly, or whether several birds are joining in.
4. Look at the flock size, space and layout to see if there may be crowding, blocked access to feeders or drinkers, or areas where a bird can be cornered.
5. Check the bird's general appearance for anything that makes it stand out, such as injury, weakness, lethargy, change in posture, missing feathers or dirty vent feathers.
6. Inspect the coop and run for boredom triggers such as limited enrichment, poor ventilation, wet bedding, muddy ground or not enough feeders and drinkers.
7. Check whether any bird in the group is stressed, unwell, moulting heavily or recently introduced, since flock tension often starts around changes like these.
Common Causes
The most common cause is normal flock pecking order behaviour that has become too rough, especially in a small or crowded group. Competition over food, water, perches or favourite resting spots can also lead to repeated pecking.
Another common cause is boredom or stress. Birds that don't have enough space, stimulation or access to resources may pick at each other more often.
Sometimes a chicken is pecked because it already looks different, for example after moulting, injury, illness or feather loss. Less commonly, a bird with a wound or skin irritation may attract more attention from the rest of the flock.
What To Do
Separate the injured bird if pecking is ongoing, so it can rest and the skin can be kept clean and easy to monitor. If the skin is only mildly affected, keep the area under close watch and check it at least daily.
Review the flock set-up and make sure there is enough space, more than one feeder and drinker if needed, and enough room for quieter birds to move away. Small changes such as adding enrichment, improving access to food and water, and reducing crowding may help lower tension.
Keep the bird's environment as clean and dry as you can, and avoid handling the injury more than necessary. If the pecking is linked to a specific bird, watch the group closely to see whether you need to separate a bully temporarily.
If the problem keeps happening, or the bird seems unwell as well as being pecked, get veterinary advice.
When To Contact A Vet
Contact a vet if the wound is deep, bleeding won't settle, there's swelling or discharge, the bird seems dull or off colour, or the pecking is getting worse despite separating the bird and improving flock conditions.
It's also sensible to get advice if you're unsure whether the injury is only from pecking or whether something else is making the bird easier to target.
Products That May Help
Keeping the coop, run and surrounding areas clean can be useful as part of your routine when you're managing pecking injuries and trying to reduce stress in the flock.
