Vent Gleet in Chickens: What It Is, What to Look For, and How to Treat It

3 min reading time

Vent gleet in chickens is a common but treatable yeast infection that affects a hen’s vent and digestive health. Learn the early signs to watch for, what causes it, and step-by-step treatment options to help your flock recover quickly and prevent future outbreaks.

If you’ve ever picked up a hen and noticed a foul smell, white discharge, or messy feathers around her vent, you may be dealing with vent gleet.

Vent gleet can look alarming — but when caught early, it’s usually very treatable. Let’s break down what it is, how it happens, and exactly what to do.

What Is Vent Gleet?

Vent gleet (also called cloacitis) is a fungal or yeast infection of a chicken’s cloaca — the internal chamber where the digestive, urinary, and reproductive tracts meet.

It is most commonly caused by an overgrowth of Candida (yeast) in the digestive system. When the gut flora becomes unbalanced, yeast can multiply and cause inflammation, irritation, and discharge from the vent.

Think of it like a yeast infection — but in poultry.

What Causes Vent Gleet?

Vent gleet usually doesn’t happen “out of nowhere.” Something disrupts the hen’s normal gut bacteria first.

• Prolonged antibiotic use
• High-sugar treats or poor diet
• Moldy feed
• Chronic diarrhea
• Stress
• Weak immune system
• Poor coop hygiene
• Internal parasites

In many backyard flocks, it starts with digestive upset that goes unresolved.

Symptoms to Look For

• White, creamy, or yellow discharge from the vent
• Foul, sour smell
• Wet, matted feathers around the rear
• Red, swollen, irritated vent
• Straining to poop
• Reduced egg production
• Lethargy
• Weight loss in chronic cases

The discharge is often described as “cottage cheese-like.” If you smell something sour or yeasty — that’s a big clue.

How to Treat Vent Gleet

Step 1: Isolate the Hen

Separate her to monitor droppings and prevent pecking from flock mates.

Step 2: Clean the Vent

• Soak her bottom in warm water with Epsom salt
• Gently remove dried discharge
• Pat dry completely
• Apply a thin layer of antifungal cream (miconazole-based athlete’s foot cream works well)

Repeat daily until improvement is seen.

Step 3: Address the Yeast Internally

Option A: Probiotics

• Add a high-quality poultry probiotic to water daily
• Plain unsweetened yogurt (small amounts) can help temporarily

Option B: Apple Cider Vinegar

• 1 tablespoon per gallon of water
• Helps support gut pH balance

Option C: Oral Antifungal (Severe Cases)

Veterinary-prescribed antifungals like Nystatin may be required for stubborn infections.

How Long Does It Take to Clear?

Mild cases can improve in 3–5 days. More advanced cases may take 1–2 weeks.

If you notice worsening swelling, bloody discharge, egg binding symptoms, or no improvement after a week, consult a poultry veterinarian.

Prevention Tips

• Keep feed dry and mold-free
• Avoid excess sugary treats
• Clean bedding regularly
• Use probiotics during and after antibiotics
• Keep waterers clean
• Perform regular flock health checks

Healthy gut = healthy hen.

Is Vent Gleet Contagious?

Not directly. The yeast is often already present in the digestive tract. However, poor sanitation can contribute to multiple birds developing symptoms if flock conditions are unhealthy.

Can You Eat the Eggs?

If the hen is otherwise healthy and not on medication, eggs are typically safe to eat.

• Discard eggs during systemic antifungal treatment
• Do not eat eggs from severely ill hens

Final Thoughts

Vent gleet looks messy and smells worse — but it’s usually manageable with quick action. Early detection makes all the difference.

If you regularly check your flock, keep their coop clean, and support gut health, vent gleet is rarely a long-term problem.
