⚠️ Symptoms of Canker in Chickens
Early detection is key to preventing serious complications. Look for these common symptoms:

- Difficulty eating or drinking due to mouth sores.
- Foul-smelling breath caused by infection.
- Swollen face or eyes in severe cases.

🦠 What Causes Canker in Chickens?
Canker is caused by the protozoan parasite Trichomonas gallinae, which spreads through contaminated water, feed, and direct contact with infected birds.
Common Sources of Infection:
- Dirty water sources (ponds, shared waterers, or puddles)
- Pigeons, doves, or wild birds carrying the parasite
- Direct contact with infected flock members
- Shared feeding stations where contaminated saliva spreads the parasite
🔹 Did You Know? Pigeons and doves are natural carriers of canker, often passing it to backyard chickens when they share water or food sources.
🏥 How to Treat Canker in Chickens
Once diagnosed, quick treatment is essential. Here are the best treatment options:
1. Natural Remedies
For mild cases, some chicken keepers prefer natural treatments:
- Apple cider vinegar (ACV): Add 1 tablespoon per gallon of water to help create an acidic environment that slows parasite growth.
- Garlic water: Crush fresh garlic into water as a natural antimicrobial solution.
- Probiotics & herbal supplements: Boost the immune system with oregano, thyme, and probiotics.
2. Medical Treatments
For more severe cases, prescription medications are often necessary:
- Metronidazole (Flagyl): The most effective antiparasitic drug used for canker treatment.
- Ronidazole & Carnidazole: Alternative options available from vets.
- Copper sulfate: Sometimes used in drinking water to prevent outbreaks.
🔹 Important: Always consult a poultry vet before administering medications to ensure correct dosage and safety.
