Chickens lose their feathers due to molting, stress, parasites, nutritional deficiencies, or diseases, impacting their health and egg production.
Feather loss in chickens can alarm backyard flock owners. While molting is natural, other causes like parasites, stress, or nutritional deficiencies require attention. Understanding why chickens lose feathers helps you take proper action.
1. Natural Molting Process
Molting is the most common reason for feather loss. Chickens typically molt annually after their first year, often in fall as daylight decreases.
How to Identify Molting
- Feathers drop in sequence: head → neck → body → wings → tail
- New pin feathers emerge as old ones fall
- Multiple birds affected simultaneously
- Egg production decreases or stops temporarily
Molting lasts 4-16 weeks. During this time, boost protein to 18-20% of their diet with high-quality feed and supplements like mealworms.
2. Feather Pecking and Cannibalism
Chickens may peck each other’s feathers due to:
| Cause | Solution |
|---|---|
| Overcrowding | Provide minimum 4 sq ft per bird in coop |
| Boredom | Add perches, dust baths, and chicken toys |
| Nutritional deficiency | Ensure proper protein (16-18%) and minerals |
According to Manna Pro, feather picking often starts as curiosity but can become habitual if not addressed.
3. External Parasites
Mites and lice cause intense itching, leading to feather loss. Check for:
Signs of Parasites
- Visible bugs near vent or under wings
- White lice eggs at feather bases
- Red or scabby skin
- Restlessness at night
Treat with poultry-safe insecticides and thoroughly clean the coop. Regular parasite control prevents reinfestation.
4. Stress-Induced Feather Loss
Stressors that may cause feather loss include:
- Predator attacks
- Extreme weather changes
- Introduction of new flock members
- Loud noises or disturbances
As noted by Chicken Coach, stressed chickens may pluck their own feathers. Provide calm environments and gradual introductions when adding birds.
5. Nutritional Deficiencies
Key nutrients for feather health:
Essential Nutrients
- Protein: 16% minimum (20% during molt)
- Methionine: Critical amino acid for feather growth
- Zinc & Copper: Support keratin production
- B Vitamins: Aid in feather pigmentation
Limit treats to 10% of diet to ensure proper nutrition from complete feeds.
6. Broodiness
Broody hens often pluck breast feathers to line nests. This is normal behavior but can appear alarming. Provide:
- Proper nesting boxes (1 per 4 hens)
- Clean bedding materials
- Space to break broodiness if needed
7. Disease or Health Issues
Some illnesses cause feather loss, including:
- Fowl pox
- Fungal infections
- Internal parasites
- Liver disease
Consult a poultry veterinarian if feather loss accompanies other symptoms like lethargy, diarrhea, or weight loss.
How to Help Chickens Regrow Feathers
Support feather regrowth with:
Dietary Support
- High-protein feed (18-20%)
- Supplement with sunflower seeds or mealworms
- Provide oyster shell for calcium
Environmental Support
- Clean, dry coop with proper ventilation
- Access to dust baths
- Protection from extreme weather
Stress Reduction
- Maintain consistent routines
- Limit flock disturbances
- Provide adequate space
