Prolapse Vent in Chickens: Causes & Treatment.

Prolapse vent in chickens, also known as prolapsed oviduct, blow-out, cloacal prolapse, or pickout, … “is a condition in which the lower part of a hen’s oviduct turns inside out and protrudes through the vent.”1  Prolapse is a very serious condition that can be treated if caught early, but is likely to recur.

COMMON CAUSES OF PROLAPSE

  • chickens that begin laying too young and are underweight
  • eggs that are too large
  • older chickens that are obese
  • a calcium deficiency
  • holding droppings for a long period of time, causing stress and stretching of the cloaca

PROLAPSE TREATMENT

  • separate from flock
  • clean protruding tissue well (I use Vetericyn after a bath)
  • replace the tissue manually
  • apply an anti-inflammatory cream such as hydrocortisone (hemorrhoid ointment was once the treatment of choice, but is no longer considered appropriate) or continue spraying with Vetericyn 2-3 times per day until healed.
  • provide vitamins and electrolytes or liquid calcium to restore the ability of the uterus muscle to contract properly
  • if tissue is compromised by pecking or is especially dirty, antibiotics may be indicated, which will require a vet visit
  • monitor vigilantly for the lifetime of the chicken

Many sources of information on prolapse indicate that chickens with prolapse should be culled. I suspect this recommendation is made for large poultry operations, not backyard chicken-keepers since prolapse is often manageable. Given that prolapse is likely to happen again, as long as the status of the hen’s condition is monitored, culling is ordinarily unnecessary. The biggest danger to a chicken with prolapse is other chickens picking at the reddened area; picking can result in hemorrhage and/or the chicken’s oviduct and/or intestines being pulled out and eventual death from cannibalism.

My plans for today did not include finding a hen with a prolapsed vent. My brother, who was visiting with his daughter, was shoveling his annual load of chicken manure into his truck while I snapped photos of my adorable niece interacting with the chickens.  It was then that I caught a glimpse of droppings stuck to Anna’s vent in the distance. Upon closer inspection, the prolapse was obvious. My brother, who is a nurse practitioner in an emergency room, was surprised to see me, the lawyer in the family, spring into action upon discovery of the prolapse and I was surprised to see him, shocked at the condition of my hen. Fortunately I discovered the prolapse before any of her flockmates and my chicken first-aid kit was stocked.
Anna was unable to pass the droppings stuck in her vent due to swelling, so I  applied gentle pressure to the sides of the prolapsed tissue to remove it. The prolapse immediately receded, but only momentarily.

I next put her into the sink, filling it with warm water to clean the droppings off her feathers and cleaned the protruding tissue with Vetericyn.  I then wrapped her in a large towel, covering her head loosely as I was working solo and this calms chickens. She sat still the entire time I worked on her.

I then gently guided the prolapsed tissue into its proper location. The concern now is in keeping the tissue in place. So far, so good. I added vitamins & electrolytes to her water for the added calcium and stress. She will be kept isolated from the rest of the flock and her access to light limited to less than 12 hours per day to discourage egg-laying, giving her oviduct time to rest.

Anna’s vent returned to normal. While Anna was relaxed and calm, it was easy to inspect her feet, both of which had early signs of bumblefoot. There was minor swelling and redness of the right foot pad with a small, telltale scab and the left foot had an even smaller scab with very little swelling.

This is a very early case of bumblefoot and the plan is to apply Vetericyn  to her feet at least twice daily, place a non-stick gauze pad on top of it and wrap her feet in Vetrap to keep the product in place. Worst case scenario, it doesn’t work and I perform bumblefoot surgery on her. Best case scenario, she is spared the pain of the surgery and is cured by the Vetericyn.

Anna and I are going to spend some quality time together this week as I keep her inside, clean and safe from her curious flockmates. I will treat both of her feet and continue to monitor her prolapse. (Stay tuned for status updates on Anna’s progress.)

UPDATE as of 10/24/12: Anna has not had a recurrence of the prolapse since the first incident, thankfully.

UPDATE: 5/27/12 Anna healed brilliantly from her bumblefoot treatment with Vetericyn. I did lance the scab in order for the product to reach the infection.

I was wondering if you could tell my why my 2 year old hen has a red swollen bum. It feels like a water balloon and all the feathers are gone from the area?

Today I went out to the coup and found my almost two years old hens not really moving. I picked her up and found a very bad case of prolapse vent. Bloody and a lot of innerds coming out. She died in my arms shortly after. Was wondering if I should be worried about her recent eggs. I have 7 laying hens and do not know which are hers. I am assuming she had an infection I didn’t catch. I am in the coup twice a day so am upset about that. But are her eggs ok to be eating?

I have a 5mo Buff Orpington who started laying about 2 weeks ago, today I found her with a prolapsed vent, I soaked her, got the egg out and cleaned her off, manually pushed the tissue back in, but it wont stay, the tissue around the edges looks light tan, I don’t know if it is poop that wont come off or dying tissue. I soaked her again hours later and still can’t get the tissue to stay in, she is also contracting. Any advice would be greatly appreciated.
Thank you
Carrie
