You know the moment. One of your girls is standing apart from the flock, not foraging, not dust-bathing, just… waiting. And when you get close, you see it: a dead leaf stuck to her vent with a glue of poop and mucus. That is not a leaf. That is a cluck-tastic cry for help, and your hen was smart enough to stand near the house and hope you'd notice.
This reader did notice, and that's the part of the story that matters most. They came back from a week-long vacation, found a three-year-old hen acting off, and didn't shrug it off. They went closer. They separated her. They cleaned her up and took a photo. Then they did the bravest thing a chicken keeper can do: they admitted they weren't sure what to do next. That vulnerability, that "I think it's a prolapse that festered", is exactly the kind of honesty that makes this community worth clucking about. It's not an expert diagnosis delivered from on high. It's a real person staring at a real problem and saying, "Help."
That dead leaf isn't the problem. It's a symptom. The real issue is what's happening inside that vent, and you've already named the most likely suspect: a prolapse that got left alone while you were on vacation. Three-year-old hens are prime candidates for reproductive issues, especially after a stressful week without their usual routine. You did the first steps right, isolation, cleaning, observation, but what comes next is harder. This hen needs a vet, not a forum. A prolapse that's been sitting for days, collecting debris and infection, isn't something to treat with ointment and prayers. It's a medical emergency.
We know that sounds like the kind of serious advice we usually avoid, but here's the playful truth: sometimes being a good chicken parent means chickening out of a DIY fix. You love this bird. She came looking for you. She trusted you to see that leaf and know it was wrong. Now trust yourself enough to make the hard call. Call your vet, describe what you found, and ask for a same-day appointment. If a prolapse is indeed the culprit, the longer it goes untreated, the less likely she is to recover. And if the vet says it's too far gone, at least you'll know you didn't let her suffer alone.
That's the concrete point: when a dead leaf tells you your girl is in trouble, clean her up, but don't stop there. Get her the real help she's asking for.
