Chickens peck each other due to boredom, stress, establishing pecking order, or nutritional deficiencies; providing enrichment and proper care can reduce this behavior.
Chicken pecking is normal behavior, but when it turns aggressive, it can lead to injuries or even death. Understanding why chickens peck each other helps prevent problems and maintain a peaceful flock.
Normal vs. Problematic Pecking
Chickens use pecking to communicate and establish hierarchy. Gentle pecks are harmless. Aggressive pecking causes feather loss, wounds, or stress.
Signs of Trouble
- Bald spots (not from molting)
- Blood on feathers or skin
- Chickens hiding or avoiding others
Top Reasons Chickens Peck Each Other
1. Overcrowding
Chickens need space. The minimum is 4 sq ft per bird indoors and 10 sq ft outdoors. Crowding increases stress and pecking. Learn more about coop size for 10 chickens.
2. Boredom
Chickens peck when they have nothing else to do. Add perches, dust baths, or hanging treats to keep them busy.
3. Nutritional Deficiencies
Lack of protein or minerals can cause feather eating. Ensure your feed has at least 16% protein. Offer calcium supplements like oyster shell.
4. Pecking Order Disputes
New birds disrupt hierarchy. Introduce chickens slowly. Read our guide on introducing chickens to a new coop.
5. Bright Lights
Constant light stresses chickens and increases pecking. Provide 14-16 hours of light max.
How to Stop Chickens From Pecking Each Other
Immediate Solutions
- Isolate injured birds until healed
- Apply wound spray or cornstarch to stop bleeding
- Use pinless peepers (blinders) on aggressive birds
Long-Term Fixes
| Problem | Solution |
|---|---|
| Overcrowding | Expand coop or reduce flock size |
| Boredom | Add perches, toys, and foraging opportunities |
| Nutrition | Switch to higher quality feed |
When to Remove a Chicken
Some birds become chronic bullies. According to Pam’s Backyard Chickens, aggressive roosters often need rehoming. Consider separating problem birds permanently.
Preventing Future Issues
- Provide dust baths (sand + wood ash + dirt)
- Install multiple feeding stations
- Offer greens or hanging cabbage for pecking
The Purina Animal Nutrition Center recommends keeping birds active to reduce pecking. Rotate their environment regularly.
Special Considerations
Molting Chickens
During molt, chickens have tender skin and new feathers. Increase protein to 18-20% during this time.
Introducing New Birds
Always quarantine new chickens for 2-4 weeks. Introduce through wire first, then supervised visits.
When Pecking Turns Deadly
Cannibalism starts with pecking. Once chickens taste blood, they may not stop. Act fast at first signs of injury. Darkening the coop can help calm aggressive birds.
