Feather issue

[WIchickens]

So my australorp, known as Truck ( yes a girl who was named by my son ) is missing feathers on both wings. It started in early spring and has gotten progressively worse. She is also missing a few on her chest area.
I got close enough today to see that it looked like they are getting pecked off but unsure by who or why. Truck is near the top of the pecking order, and there are only 5 of them! Could this be from something else or just bullying??

I had a bantam mix that was beating on my bearded Belgium d'anver this looks really similar to what happened with my chickens

No problem I ended up getting rid of the mutt since she was too loud for where I live and that's where the problems stopped
