Why is my rooster bullying the hens?

Overview
A rooster bullying hens is often related to mating behaviour, flock hierarchy, stress, or not having enough space. Sometimes it’s a normal but over-strong rooster pattern, but repeated chasing, feather damage or injured hens means the situation needs attention.
There can be more than one cause, so it helps to watch the flock closely before you decide what to change.
Things To Check
1. Watch when the bullying happens. It may be linked to feeding time, turnout, dusk, or when the rooster is trying to mate.
2. Check whether one hen is being singled out or whether several hens are being chased, pinned or pecked.
3. Look for signs of injury such as missing feathers, broken skin, swelling, scabs or a hen avoiding the rooster.
4. Assess space in the run and coop. Crowding can make normal flock behaviour much sharper and harder on the hens.
5. Look at whether the flock has enough feed, water, hiding spots and places for hens to move away.
6. Check if anything has changed recently, such as a new bird, a change in housing, new nesting areas or a smaller run.
7. Listen and watch for broader flock tension, like persistent pecking, chasing or hens seeming too nervous to feed normally.
Common Causes
The most common reason is mating behaviour that’s become too frequent or rough for the hens. Some roosters are simply more persistent than others.
Another common cause is flock stress, often from overcrowding, limited resources or a recent change in the group. When birds can’t get away from each other, bullying can become more obvious.
Feather pecking, poor flock balance, or a rooster that’s not settled into the group can also play a part. Less commonly, illness, pain or discomfort in the flock can change behaviour and make interactions more aggressive.
What To Do
Start by watching the flock at different times of day so you can work out the pattern. If the rooster is repeatedly bothering one hen, give that hen a chance to rest from him by separating birds temporarily or adjusting how they’re housed, if you can do so safely.
Make sure there’s enough space, more than one feeder and drinker if needed, and places for hens to move away and hide. Small changes to the environment can sometimes reduce tension quite a bit.
Keep an eye on feather loss, skin damage and whether the hens are eating, drinking and behaving normally. If the behaviour is steady but not causing harm, monitoring may be enough. If it’s escalating, the rooster may need closer management or rehoming within the flock.
When To Contact A Vet
Speak to a vet if a hen has broken skin, swelling, heat, bleeding or seems unwell, or if bullying has led to reduced eating, marked stress or obvious injury. A vet can help you work out whether there’s underlying pain, illness or another health issue affecting the flock.
Products That May Help
If you’re managing flock behaviour, coop cleanliness and day-to-day housing can make it easier to keep an eye on changes in the group and maintain a calm routine.
