Most backyard flocks stay healthy with clean housing, fresh water, and a good diet. But knowing the common problems helps you catch trouble early.
What a healthy bird looks like
Bright red comb, clear eyes and nostrils, active and alert, eating and drinking, glossy feathers, firm droppings. Learn your birds’ normal so you notice when something’s off.
Common illnesses
- Coccidiosis — the big one in chicks. A gut parasite causing lethargy and bloody or runny droppings. Prevent with medicated starter feed; treat promptly with amprolium. Keep brooders clean and dry.
- Respiratory infections — sneezing, rattly breathing, bubbly eyes, nasal discharge. Isolate the bird, keep it warm, and consult a vet — some respiratory diseases are contagious and lifelong.
- Marek’s disease — a viral disease causing paralysis and tumors in young birds. There’s no cure, so vaccinate chicks at the hatchery and practice good biosecurity.
- Egg binding — a hen straining, hunched, and not laying. A warm bath and calcium can help; see a vet if it persists.
- Sour or impacted crop — a squishy or hard lump at the throat that doesn’t empty overnight.
- Worms — gradual weight loss and messy vents; deworm as advised by a vet.
Prevention beats treatment
- Keep the coop clean, dry, and well-ventilated.
- Provide constant fresh water and a complete feed.
- Quarantine new birds for two weeks.
- Limit visitors’ contact with your flock (biosecurity).
This is general information, not veterinary advice. A sick bird that isn’t improving should see a poultry vet — and isolate it from the flock in the meantime.
