Why are my chickens pecking one bird more than the others? | arlo.® Atlas

Overview

If your chickens are pecking one bird more than the others, the most common reason is that the flock has singled her out. This can happen with feather pecking, bullying, or after a change in the group, housing or routine. It doesn’t always mean something serious, but it does mean that bird needs checking closely.

In many flocks, one bird becomes a target because she looks different, is quieter, is weaker, or has broken feathers or skin that catch the others’ attention. Stress, boredom, crowding and parasites can also make pecking worse.

Things To Check

1. Watch when the pecking happens, such as after being let out, at feeding time, in the evening, or when the flock is confined.

2. Look closely for bare patches, broken feathers, redness, scabs, bleeding, or a bird that seems nervous, hunched or withdrawn.

3. Check whether anything has changed recently, including a new bird, a moved coop, less space, different feed, or altered lighting.

4. See if the target bird is smaller, moulting, unwell, slow to feed, or missing feathers around the tail, back, vent or neck.

5. Check the coop and run for crowding, limited feeders or drinkers, wet bedding, poor ventilation, or not enough perch and scratch space.

6. Look for signs of parasites or irritation, such as constant preening, restlessness, feather loss, or dust bathing more than usual.

7. Notice whether the pecking is mild and brief, or whether one bird is being chased, pinned away from food, or repeatedly attacked.

Common Causes

The most common cause is normal flock pecking order behaviour that has become too focused on one bird. Chickens often pick on a bird that seems different, vulnerable or easiest to dominate.

Another common cause is stress. Overcrowding, boredom, poor enrichment, changes to the flock, or limited access to food and water can all make pecking more likely.

Moulting, feather damage, or a bird with bare skin can also attract more pecking, because the other birds notice the change and keep going back to it.

Less commonly, an underlying health problem, parasites or discomfort may make one bird slower or weaker, which can increase her risk of being targeted.

What To Do

First, separate any bird that is being badly bullied or is bleeding, so the pecking doesn’t escalate and the wound can be kept clean and watched.

Make sure the flock has enough space, several feeding and drinking points, and somewhere quieter for a targeted bird to get away from the others.

Keep the environment busy with routine, fresh bedding, and safe enrichment such as scattering feed, so the birds have more to do and less time to focus on one another.

Check the targeted bird daily so you can spot new damage early. If feathers are missing, look for the cause rather than just the bare patch itself.

If the behaviour started after a change, try to think through what altered first. Small management changes often make a bigger difference than people expect.

When To Contact A Vet

Contact your vet if the bird has bleeding that won’t settle, deep skin damage, marked swelling, seems unwell, stops eating, or is being repeatedly attacked and cannot safely stay with the flock.

You should also seek advice if feather pecking is sudden, severe, or keeps happening despite improving space, feeding access and flock management.
