Chickens may have diarrhea due to infections, parasites, dietary changes, or consuming contaminated food and water, affecting their digestive health.
Chicken diarrhea is a common but serious issue that can signal underlying health problems. While occasional loose droppings are normal, persistent watery stool requires immediate attention. This guide explores the causes, symptoms, and treatments to keep your flock healthy.
Normal vs. Abnormal Chicken Droppings
Healthy chicken poop has two parts:
- Brown solid fecal matter
- White urate cap (chickens excrete urine as paste)
Diarrhea appears as:
- Watery, unformed droppings
- Foul odor
- Feathers caked with stool
Caecal Poops: Don’t Mistake These for Diarrhea
Caecal droppings are pasty, smelly, and dark brown/black. They’re completely normal, making up about 30% of droppings. Unlike diarrhea, these occur occasionally rather than consistently.
Common Causes of Chicken Diarrhea
1. Bacterial Infections
- E. coli: Causes severe intestinal inflammation
- Salmonella: Leads to watery green diarrhea
- Clostridium perfringens: Results in necrotic enteritis
2. Viral Infections
- Newcastle disease
- Avian influenza
- Infectious bronchitis
3. Parasitic Infections
Coccidiosis (Most Common in Chicks)
This protozoan infection causes bloody diarrhea and high mortality in young birds. Regular deworming helps prevent outbreaks.
4. Dietary Issues
- Moldy feed
- Sudden diet changes
- Excess protein/fat
- Lack of grit
5. Environmental Stressors
- Heat stress (above 29°C/85°F)
- Overcrowding
- Poor ventilation
Identifying Specific Conditions
| Condition | Diarrhea Appearance | Other Symptoms |
|---|---|---|
| Coccidiosis | Bloody, watery | Lethargy, ruffled feathers |
| Fowl Cholera | Greenish-yellow | Blue combs, breathing issues |
| Heat Stress | Watery | Panting, wings spread |
Treatment and Prevention
Immediate Actions
- Isolate affected birds
- Provide electrolytes in water
- Clean coop thoroughly
- Replace bedding
Long-Term Prevention
- Vaccinate against common diseases
- Maintain proper coop size to prevent overcrowding
- Use probiotics in feed
- Implement biosecurity measures
When to Seek Veterinary Help
Consult a vet if:
- Diarrhea persists more than 2 days
- You see blood in droppings
- Multiple birds are affected
- Birds show lethargy or loss of appetite
For severe cases, vets may prescribe antibiotics like Tylan 50 or Corid for coccidiosis.
Special Considerations
Chicks vs. Adult Birds
Chicks are more susceptible to coccidiosis. Treat immediately at first signs – delay can be fatal.
Broilers vs. Layers
Meat birds may develop diarrhea from rapid growth diets. Layers might show issues during molting periods.
