About Internal Infection / Lethargy
Lethargy is a sign, not a diagnosis. Infection is one possibility, but reproductive problems, parasites, poor nutrition, injury and environmental stress can also make a chicken unwell. Testing may be needed to find the cause.
Signs to look for
- Unusual stillness, hunched posture or withdrawal
- Eating less, weight loss or changed droppings
- Reduced laying, breathing changes or difficulty moving
What can cause it?
Several illnesses share these signs. Do not assume that every tired hen has a bacterial infection or needs antibiotics.
First steps and veterinary care
Contact a poultry-experienced vet promptly. Keep a record of when signs began, birds affected, feed changes and recent arrivals. If safe, provide a quiet separate pen with suitable temperature, ventilation and easy access to water and normal feed.
Prevention and everyday support
Use clean equipment, dry housing, appropriate feed and a quarantine plan agreed with your vet. Observe the flock daily so changes are noticed early.
When to seek help
Collapse, inability to drink, severe breathing difficulty or rapid deterioration need emergency veterinary help. Multiple unexpectedly sick or dead birds should also be reported to the Australian Emergency Animal Disease Hotline.
