Missing patch of feathers (small of back)

My Barred Rock has had this patch missing for 2 months now. Wondering what it’s from. The rest of the birds (7) are fine.

Do you have a rooster? That is typically caused by being overbred by a rooster.

I do and that’s what I was leaning towards. Funny thing ia that I typically see him on every other hen.
