Pendulous Crop is a chicken health condition. Pendulous crop is chronic and predisposes to aspiration and secondary infection. Monitor closely; may eventually require culling if bird cannot maintain adequate nutrition. This guide covers what to watch for, causes, treatment, and prevention strategies.
What It Looks Like
Watch for these signs:
Crop (proventriculus area) / breast: Crop appears as a large pouch on the breast, visibly hanging and swinging when bird moves
Crop (neck area): When you gently press the crop area, it feels abnormally large, mushy, and retains food
Mouth / crop: Bird regurgitates or vomits feed; sour smell may develop if Candida colonizes the baggy crop
Behavior / digestive: Bird pecks but seems to struggle with swallowing; eats less than normal
Growth / body condition: Bird appears thin or fails to gain weight despite eating
Respiratory / lungs / general: If crop ruptures, contents can be aspirated; bird may cough or develop pneumonia
Likely Causes
- Chronic overeating or feeding large, indigestible particles that stretch crop tissue
- Repeated or chronic sour crop (Candida infection) causing crop wall degradation
- Crop obstruction or impaction causing stretching from pressure
- Poor quality feed or contaminated feed promoting crop dysfunction
- Genetic predisposition in some birds (condition runs in families/breeds)
- Age or wear: repeated cycles of stretching eventually cause permanent damage
- Nutritional deficiency affecting tissue repair and muscle tone
About This Condition
Body System Affected: Digestive system (crop); chronic stretching and weakening of crop tissue
Severity: moderate
Contagious: No, not contagious
Affected Age Groups: pullets, hens
What to Do
No cure; management is palliative. Feed small, frequent meals of soft food (soaked pellets, cooked grains) to ease digestion. Provide probiotics to prevent secondary Candida. Keep bird isolated to prevent stress. Monitor for signs of aspiration (coughing, wheezing, lethargy). If secondary sour crop develops, treat with antifungals. Severely affected birds may require culling for humane reasons.
When to See a Vet
If you see signs of secondary infection (sour smell, regurgitation, lethargy), aspiration (coughing, respiratory distress), or if the bird stops eating effectively.
Prevention
Avoid overfeeding; provide measured portions. Feed quality pellets rather than mixed grain (prevents selective eating of indigestible material). Avoid feeding large, hard pieces (corn kernels, stones). Treat sour crop aggressively to prevent crop wall damage. Provide probiotics routinely.
Frequently Asked Questions
Q1: What is the difference between pendulous crop and sour crop?
Pendulous crop = CHRONIC STRETCHING: crop tissue is permanently weakened and enlarged; bird cannot fully empty it. Sour crop = ACUTE/TREATABLE: Candida infection, soft and mushy, reversible with antifungals. HOWEVER, repeated sour crop can cause pendulous crop. Different diseases, but sour crop can progress to pendulous crop.
Q2: Can pendulous crop be cured?
No. Once crop tissue is permanently stretched and weakened, it cannot be repaired. This is a chronic condition requiring lifelong management or eventual culling.
Q3: Is pendulous crop life-threatening?
Not immediately, but birds are at risk for aspiration (inhaling crop contents into lungs) if crop ruptures. Secondary Candida infection can develop. Quality of life is reduced.
