I love the name Roadrunner. It's perfect for a hen who treats every human approach like the opening scene of a Looney Tunes short. But when that same speed demon has a bleeding vent and you're standing there with no vet and a head full of worst-case scenarios? The humor evaporates fast. DragonEmpress4, you are not alone in this panic, and your fear is not silly.
First, the practical stuff. A hen who isn't laying yet, at six to seven months, is not unusual, some ladies take their sweet time. But a bleeding vent with discharge, especially when she's pecking at it herself, is a red flag you should not ignore. It could be a prolapse, an infection, or even an injury from that rehomed rooster. The pecking is her trying to fix something she doesn't understand, which only makes it worse. You need a vet. I know you don't have one yet, that's not a judgment, it's a reality for many of us, but this is the moment to find one. Call a local avian vet or even a farm supply store that works with poultry. Ask for a recommendation. Roadrunner might be fast, but bleeding doesn't wait for her to slow down.
Now for the emotional part, the part where you feel like a bad chicken parent. You're not. You rehomed a rooster because you saw a problem. You check on your girls. You care enough to ask strangers on the internet for help. That is not negligence; that is the messy, humbling work of learning. Chickens will humble you every time. They bleed, they hide, they run. And then they make you feel like a fool for panicking, until they don't, and you realize your panic was justified. Trust your gut. If it looks wrong, it probably is.
Our take? Get Roadrunner to a professional. Separate her from the flock so the others don't peck at the wound. Keep the area clean. And when you bring her home, give her some extra mealworms and a quiet corner. You've got this. Just don't try to catch her by chasing, she'll win. Trap her in the coop or use a net. Then breathe. You're learning the chicken dance, and the first step is always a stumble.
