Permanent solitary hen?

[chickndays]

What do you do when you can no longer keep a hen with the others?
One hen must've bled while laying an egg and the others took some layers of skin off the back end. I have tried to reintroduce it back again and again but this time it wasn't in there five minutes before another hen was pecking it and chasing it so now it has some prolapse and I again removed as quickly as I could. It has been living in the garage and an auxiliary coop beside the main one and is living there again. Is there something to cover up the backside below the vent that would actually stay on?

Was the hen completely healed when you put her back? How long had she been separated? If she's wasn't completely healed, then they were just going after the injury. If she was and had been gone for awhile (longer than three days), then they were settling pecking order (which, this sounds more like injury specific than pecking order).

She should be completely separated until she's healed. Then once she's healed, you'll have to work on introducing her back to the flock. It's typically hard to introduce one bird, but not impossible. I've found sneaking the "new bird" in after dark is a lot easier than any other method, though it will still take two weeks for the pecking order to be completely settled.
