Prolapsed Vent (Cloaca) and Laying Problems in Hens



By Vicki -


A prolapsed vent on a laying hen occurs when there is degeneration to the muscular system responsible for laying - it is a form of herniation. There are a number of possible reasons a hen can develop a prolapsed vent; it can occur when the shell of eggs is not forming properly due to a lack of calcium. Soft shelled eggs are harder to pass through the oviduct and can cause this strain injury. Hens can also be more prone to this injury if they are being forced to continue laying beyond their natural laying cycle (by using lamps to force laying in the sorter days of winter). A hen may also have issues with her conformation that make her more prone to develop a prolapse (pinched tail, wry tail and other bone or muscular issues).

 To help prevent a prolapsed vent:
1) Provide enough space for the hens to walk and scratch. This retains the muscle health of the hen.
2) Allow your flock to follow a natural laying cycle by not lighting the coop in the winter.
3) Provide a free-choice calcium supplement in its own container.
4) I have also read that common weed, Shepherds Purse (Capsella bursa-pastoris), provides a general boost to chicken health.
5) Provide a good diet.
6) Provide plenty of sunshine and fresh air.

However, if your chicken already has a prolapsed vent (signs: swollen red bottom, blood, egg oozing from cloaca, other hens pecking at her vent), you have to treat her.

There are common and effective ways to treat your hen. The first step is to remove the hen from the flock to prevent cannibalization. Reduce the hens feed (or even don’t feed her for one day) to interrupt laying. This will give her a much needed break in laying. I never recommend adding lights to induce laying. If your birds are not laying there is a reason.

Effective herbal care:
Wash the protruding organ in lukewarm water and using a natural oil (linseed oil or sweet oil), gently press the vent back into the body. Repeat several times as needed. Then wipe the vent area with a cloth or cotton ball that has been soaked in witch hazel (Hamamelis virginiana).

Witch hazel is an astringent and anti-inflammatory that tightens skin, soothes, reduces swelling. It is used, among other things, to relieve the pain of hemorrhoids and bruises.


Effective non-herbal care:
Wash the protruding organ in lukewarm water and using petroleum jelly, gently press the vent back into the body. Repeat several times as needed. Then treat the vent area with a combination of Preparation H and antibiotic ointment. Preparation-H reduces the swelling tissue and allows the tissue to recede.

Continue these steps until the hen is healed.

In the event of a severe prolapse (if you truly do not wish to cull the bird), a purse suture to the cloaca may be needed. Contact your local veterinarian to find out if they can provide this procedure.  If it happens a second time, I personally would cull the as it will likely be a continuing problem for the life of the bird.

  4. oh well we just had a silkie lay her first egg but unfortunately it didn't go well it has prolapsed,the egg was out suspended in membrane etc we managed to get the egg out and pop it back in again but the prolapse is making its way back out again!its been 3 days now and shes fine but im worried about further egg laying etc with her is there any way of stopping her from ever laying as we would rather she stayed a pet than an egg layer? and what if it never goes back in properly but she remains fine,i feel this is just a waiting game that I don't really want to play as im scarred every time I check incase it has happened again and we have to repeat it allover it just isn't fair on the bird x

    1. There is no way to prevent chickens from laying eggs that I am aware of.

      Have you tried Preparation-H? and the steps above? If not, please try that first. If it continues happening and you really don't want to cull this Silkie, you will need to take her to the vet and have a stitch put in to prevent the vent from prolapsing again. Look for "Avian Specialists" near you as many vets don't work on birds.

      Good luck with her!

    1. Many breeds of chickens do stop laying by 4 years of age, but if you don't plan on culling this hen, you do need to treat her for mites (wood ash rubbed in nice and deep beneath her feathers will do the trick) and treat any vent issues. Try Preparation-H and see if it helps. Otherwise, cull her if she seems to be suffering.

      For more information on getting rid of the mites, please see our "Article Index" page.

  6. Interesting we have just had a chicken "come down" with this. We have been using a heat lamp to keep them warm at night, but after reading this I think we need to come up with another solution..

    1. Yes - unfortunately prolapses don't fix themselves. Best of luck with her!

  7. Your site is very helpful. My 1.5 year old hen prolapsed after laying her second egg following her first molt. I gave her a bath and tried to push her vent back in, but it was too swollen. The vet cleaned the area with medical-grade dextrose and gave her .50 ml of Lupron, which is supposed to make her stop laying for a couple of weeks. The vet recommended that she sleep inside for about one week, but I take her outside for a few hours everyday because she was not eating while inside. For now, everything looks great. In the future, I will forgo a vet visit and just try pushing the vent back in myself with some lubricant and q-tips...now that I know how.

    1. Yes, you can try helping her at home, but be aware that it is not a good sign for a hen to develop a prolapse at such a young age. Are her eggs huge? If not, take a close look at her diet. Too much fat around the vent area can cause issues with prolapse even if the eggs are a normal size. If she is carrying too much fat, try cutting out all scratch and sunflower seeds and feed only a 15% protein feed for a while. This tends to be a bigger problem in birds that don't free range on a daily basis as there are limited ways for a hen to exercise in a pen. Good luck and let us know how she does!
