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
older chickens that are obese
- a calcium deficiency
holding droppings for a long period of time, causing stress and stretching of the cloaca
separate from flock
- clean protruding tissue well (I use Vetericyn VF 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
- consider antibiotics if tissue is compromised by pecking or is especially dirty
- if tissue will not stay in place, follow instructions at this link to carefully bandage/diaper as described
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 protrusion with Vetericyn VF hydrogel. 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 applied Preparation-H to my gloved finger first in order to shrink the swollen tissue and 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. 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. The uterus has not prolapsed since the first time.
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 VF 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: 5/27/12 Anna healed brilliantly from her bumblefoot treatment with Vetericyn VF hydrogel. I did lance the scab in order for the product to reach the infection and I am thrilled with the result!
