No just skin and down

Is there a bully who could be picking on her, or a possible feather eater?

A few have had problems where our roo’s dodgy feet have pulled out feathers while mating but that’s an accident

Now that you mention a rooster, it can be rooster damage. I've seen it on the front of some of my hens. It's caused by their bellies/chests rubbing on the ground during the mating process.
