In poultry, recognising a disease early is the difference between treating a few birds and losing a batch. This is a quick index — each entry links to a fuller guide.
The common diseases
- Newcastle disease — gasping, twisted neck, green droppings, sudden death. Prevented by the routine vaccination schedule.
- Gumboro (IBD) — watery droppings, ruffled feathers, sudden death in young birds. See Gumboro prevention and control.
- Coccidiosis — bloody or brown droppings, weight loss. See coccidiosis symptoms and treatment.
- Bird flu (avian influenza) — sudden death, blue comb and wattles. Report it immediately. See bird flu in poultry.
- Worms — slow growth, pale comb, worms in droppings. See worms in chickens.
- White diarrhoea (pullorum) — white, pasty droppings in chicks. See white diarrhoea in poultry.
- Fowl pox — scabs on the comb and wattles; slow to spread but weakens birds.
- Heat stress — panting, wings held away from the body. See heat stress signs and prevention.
The first sign something's wrong
Watch behaviour, droppings, breathing and feed-and-water intake. A change in any one is enough to act on — see symptoms of a sick chicken.
Prevention beats cure
Most of these diseases enter the farm through people, vehicles and new birds. Good biosecurity stops them at the gate.
Key takeaways
- Learn the early signs of each common disease.
- Newcastle, Gumboro and coccidiosis are the usual suspects.
- Bird flu must be reported — don't treat it yourself.
- Biosecurity prevents most of these at the gate.
