Today my son noticed that his favorite guinea hen, Minnie aged 3, had a prolapsed vent. I was in the middle of doing a bunch of other chicken chores so she had to wait for treatment. While she waited she first stood up almost vertical & was straining, only passing tiny bits of poop. Then she wandered off to another part of the yard. When I was ready to administer treatment I told my son to go fetch her. He returned holding her by her wing joints, far away from his body. "Why are you holding Minnie like that?" "There's all this stuff coming out of her!"
When he handed Minnie to me there still was stuff coming out of her -- some blood & some poop, a tiny shell-less egg, some fluid, and some stuff that looked like scrambled egg. And her bottom was a fright, big red protrusion & a second one that looked like a balloon.
But thank the Lord, I just took a folded paper towel, squirted some antibiotic ointment on it, & pressed it to her bottom, and everything slid back inside. Then I took another folded paper towel, squirted some Prep H on it, & pressed it to her now inverted vent. I held her upside down for a few minutes, holding the paper towel to her vent. Then I put her in the hospital pen with some water and her favorite food, some chick feed wetted with water.
We're praying for her full recovery, and will keep her confined & under close observation for several days or more, to see if she will need further attention. I myself expect to have some alarming dreams over the next few nights...
