This episode explains coccidiosis in chickens and duck, what it is, how it damages the gut, and why it can be fatal if left unchecked. The discussion covers how this microscopic parasite spreads through contaminated environments, the signs to watch for in backyard flocks, how vets diagnose it using poop samples, and the key steps in treatment and long-term prevention through hygiene, housing, and smart flock management.
Podcast Summary: Understanding Coccidiosis in Chickens
- Coccidiosis is caused by a microscopic parasite that invades and destroys the gut lining, leading to diarrhoea, bleeding, and secondary infections.
- Each bird species has its own coccidia; chickens, ducks, and other poultry can share some strains, but pets like dogs do not catch it from birds.
- Young or stressed birds are most vulnerable and can become very ill or die quickly without intervention.
- In the environment, coccidia form tough, long-lived spores that thrive in moist, dirty, or overcrowded housing.
- Poor hygiene, damp bedding, contaminated feeders, dirty water bowls, and overcrowding strongly increase infection risk.
- Common signs include diarrhoea (often mucous or bloody), weight loss, reduced growth, pale combs and wattles, lethargy, and reduced egg laying.
- Diagnosis is done by faecal testing — a vet examines droppings under a microscope to check for high levels of coccidia.
- Treatment involves medicated drinking water, typically over several days, followed by tapering to help birds develop immunity.
- Only specific medications (like amprolium) are safe for laying hens; others are restricted to meat birds.
- Prevention relies on clean, dry coops, fresh bedding, raised feeders, clean water, starter feed with coccidiostats, and quarantine for new birds.
