Bare Spot on Hen's back!

[want2know]

On of my hens suddenly has a bare spot on her back. She did lose some of her saddle feathers from a rough rooster a few months ago (and hasn't grown them back yet), who is out of the flock now. I checked her for mites/lice just the other day, and didn't see anything. What could this be?

No, mites or lice.

Thank you for sharing this! I will keep that in mind

Fortunately, it is shady for the most part in their runs.
