Missing feathers on back but not molting?

[Ccort]

I came home and noticed one of my girls missing a lot of feathers on her back. Pic below. This doesn't look like molting to me but please tell me if I'm wrong? Could something be wrong here?

Do you have a rooster?
It is the right season for molting.
How old?

No rooster.

Perhaps it is feather pecking/plucking.

Since you don’t have a rooster, it’s likely either feather picking or molting. I do see a lot of pinfeathers, so I’m thinking it’s a combination of both. Hens tend to pick out each others feathers when they’re bored.

I haven't seen any of the others picking at her so maybe it is molting but it seems like a lot gone quite quickly. Hopefully just molting!
