Short answer: Vent gleet is inflammation of the vent, usually with a sticky, sour-smelling discharge that matts the feathers around the opening. Yeast, most often Candida, is the common cause, with bacteria sometimes involved. Damp litter, dirty nest boxes, diarrhoea and some feed or vitamin problems make it more likely. Clean the vent gently, keep the bird dry, and follow your vet's advice on any topical treatment, because the same signs can hide a prolapse or a stuck egg.
Key takeaways
- A sticky, crusted vent with a sour smell is the sign. Check every hen's vent once a week.
- Damp, dirty litter and nest boxes are the most common reason it comes back after treatment.
- A course of antibiotics can let yeast take over, so do not start one for a sticky vent without your vet.
- Diarrhoea and poor feed leave birds more open to it. Fix the cause, not only the vent.
- The same vent signs can mean a prolapse or a stuck egg, so look closely before you treat.
The crust under the tail
You pick up a hen to check her weight and find her tail feathers stuck together with a grey-yellow paste around the vent. It smells sour. She is still eating and laying, but she is not as keen on the nest as before. That is how vent gleet usually arrives: quietly, on one bird, and easy to miss if you only look at the flock from the door.
Make it a routine to look at the vent of every hen once a week. When the birds are roosting at night it takes seconds, and it is the fastest way to catch a problem while it is still small.
What vent gleet is
Vent gleet is a name for inflammation of the vent and the tissue just inside it. The discharge is sticky, often yellowish or grey, and it builds up on the feathers around the opening. The skin can look red and sore, and the bird may keep trying to clean herself with her beak.
The usual cause is an overgrowth of yeast, most often Candida, sometimes with bacteria involved. Other organisms can look similar, so your vet may take a swab to rule them out. That is why a guess from the shop is a poor start. You want to know what you are treating before you treat it.
What a healthy vent looks like
A healthy vent is clean, dry and tucked into the feathers. The feathers around it are free of crust, the skin is pale or pinkish without a raw edge, and there is no smell beyond the ordinary smell of a bird's droppings. Lift the tail feathers and the opening should simply be there, with nothing stuck to it.
Keep that picture in your head when you check the flock. Once you have looked at a dozen clean vents, a sticky one stands out at once. Farmers who check only the birds that look unwell are checking too late, because gleet often starts on a bird that is still eating and laying normally.
Vent gleet or something worse
Several vent problems look similar at a glance. Use this table before you reach for any cream.
| Condition | What you see | What separates it |
|---|---|---|
| Vent gleet | Sticky grey or yellow crust, sour smell, sore skin | No tissue outside the vent and no hard egg |
| Prolapse | Wet pink or red tissue pushing out | Tissue protrudes and bleeds when touched |
| Stuck egg | Straining, a hard egg visible or felt | The hen is in pain, strains and makes long nest visits |
| Loose droppings soiling the vent | Watery droppings all over the feathers | The mess is on the whole rear end, not a thick crust at the vent alone |
Pasty butt is a separate problem, and it belongs to chicks. Our guide to pasty butt in chicks covers it. For adult hens, the real risk is mistaking a prolapse or a stuck egg for a simple vent infection, and that delay can cost a bird. Our guides to prolapse in laying hens and the egg-bound hen cover those two in detail.
Why damp houses bring it back
Yeast likes warm, wet and dirty places, and a poultry house in the rainy season offers all three. Wet litter by the drinkers, a leaking nipple, or nest boxes that have not been changed for weeks give yeast a place to grow, and the birds' own droppings keep it going.
In the harmattan the problem takes a different form. Dust builds up in the nests, and birds settle in the same dirty corners night after night. The air is dry, but the litter under a dripping drinker stays wet. Walk the house and find the damp spots, because one leaking drinker can keep a whole row of birds at risk.
Feed, vitamins and the antibiotic trap
Feed matters more than most farmers think. Mouldy feed, feed kept in a hot damp store, or a ration short of vitamins can leave birds run down, and a run-down bird is more open to infection. Deficiencies, especially of vitamin A, are sometimes linked with vent problems. A good layer ration with a proper vitamin pack covers most farms, and our layer feeding guide explains what a laying ration should contain at each stage. Check the date on every bag, and keep feed off the floor and dry.
Antibiotics need a warning. A course can clear some bacteria and leave yeast free to grow, so a bird with a sticky vent can end up worse after the wrong medicine. If your vet has prescribed a course, finish it as directed. Do not start one because a bird has a crust. Follow your vet's advice on whether any treatment is needed at all, and on which product to use.
Cleaning the bird, step by step
- Catch the hen quietly and hold her under one arm, with her tail towards you.
- Check the vent first for swelling, tissue or an egg. If you see any sign of prolapse or a stuck egg, stop and call your vet.
- Soften the crust with clean, lukewarm water on a soft cloth, and lift it away gently. Do not scrape the skin.
- Dry the area with a clean cloth, and keep her out of direct sun while the skin is raw.
- Put her in a clean, dry pen to rest, and check that she is eating and drinking.
- Repeat the look the next day. If the discharge comes back, call your vet.
Use a treatment only if your vet has recommended it, and show them what you have been using. A strong disinfectant on raw skin can burn the bird and make the sore worse. If your vet prescribes a topical cream, apply it exactly as they advise, and keep the bird separate until the skin has healed.

Keeping the rest of the flock clear
Vent gleet does not usually spread like a fast virus, but it can move through a flock that shares the same dirty litter, nest boxes and drinkers. When you find one bird, check the vents of the birds sitting near her, and look at the nests they use.
Change the soiled bedding in the nest boxes every few days and remove wet litter at once. Wash the drinkers in clean water, and check that none of them drips onto the floor. Put a fresh layer of dry litter down once a week, and clear the droppings boards before they build up.
Worms, mites and feed storage
Worms and mites can leave birds run down or itchy, and a flock carrying a heavy load of either is more prone to vent problems. Our guides on worms and deworming and mites and lice cover what to look for and how to control them with your vet.
Feed storage belongs on the same list. Damp, mouldy feed is a source of spores and toxins, and a bird eating it is under extra stress. Our guide to feed storage and aflatoxin explains how to keep the store dry and the stock rotating. If the feed smells musty or has visible mould, do not feed it, and ask your vet what to do with the rest.
Two hundred hens and one weekly look
Say you keep 200 hens and look at every vent once a week. With a helper it takes perhaps 20 minutes, and most weeks you will find nothing. When you do find a crusted bird early, you can clean her in five minutes and avoid an infection that takes two weeks to clear.
Now count the cost of the other path. A hen laying at 0.8 eggs a day who stops laying for three weeks costs you about 17 eggs. At GH₵50 a crate of 30, that is roughly GH₵28 of eggs, plus the feed she still eats while she is off lay. Twenty minutes a week is a small price to pay against that.
Prevention checklist
- Check every hen's vent once a week, and write down any bird with a crust.
- Fix leaking drinkers and damp litter before the rains set in.
- Change nest litter every few days, and keep the nest boxes dry.
- Store feed dry and off the floor, and use the oldest bags first.
- Keep the house ventilated so the air does not stay damp at night.
- Separate any hen with a sore or crusted vent until she is clean.
- Call your vet before starting any antibiotic or topical treatment.
Our guide to disinfectants and footbaths covers how to keep the house routine clean without harming the birds.

Questions farmers ask
Is vent gleet contagious?
It can spread through a flock that shares dirty litter, nest boxes and drinkers, so treat it as a flock issue as well as a single-bird one. It does not usually jump between birds like a virus. Clean the house, check the other birds' vents, and look at the litter and drinkers. If several birds have it, call your vet.
Can I use a human antifungal cream?
Do not use any human cream or ointment on a bird without your vet's advice. Some products contain ingredients that are unsafe for birds, and a thick cream can trap moisture against the skin. Ask your vet which product is suitable, how often to apply it, and how to keep the area clean while it works.
How do I know it is not a prolapse?
Look closely. A prolapse is soft, wet tissue that sticks out and bleeds when touched. Vent gleet is crust and discharge on the feathers around the opening, with no tissue outside the body. If you are unsure, separate the bird and send a photograph to your vet the same day.
Will the hen lay again?
Usually, yes, if the infection is caught early and she is kept clean and eating. A bird that has been sick for a long time may lose weight and lay less for a while. Give her clean water, good feed and rest, and watch her lay pattern for two weeks.
Is wiping it with a wet cloth enough?
Cleaning is a good start, but if the crust keeps coming back the cause is still there. Look at the litter, the nests, the drinkers and the feed. A bird that keeps getting sticky vents usually has a house, parasite or diet problem that wiping does not solve.
Why does it show up more in the rainy season?
Rain brings damp into the house, wet litter at the drinkers and cold, damp nests, and yeast grows fastest in those conditions. A house that is dry in the dry season can turn damp through a leak or a blocked gutter. Walk the house after every heavy rain and fix leaks before the next night.
What if the bird stops eating?
A hen who stops eating with a sore vent is sick, not just dirty. Separate her, keep water close, and call your vet that day rather than waiting to see if she improves. Loss of appetite can mean a prolapse, a stuck egg, a spreading infection or something else entirely.
Does a sticky vent always mean a hen will stop laying?
No, not always. Many birds with mild vent gleet keep laying, especially when the problem is caught early. A bird that is in pain, refusing feed or losing weight is more likely to drop lay. Watch her egg count on your lay chart, and if it falls for more than a few days, call your vet.
How often should I check the vents?
Once a week for the whole flock is a sensible minimum, and every day for any bird you have treated or separated. Do the check at night when the birds are roosting, because they are calm and easy to handle. Write down any bird with a crust, and look at her again the following week.
