Chickens wing feathers falling out

[EmsJ]

Hello my chicken is loosing her feathers on both wings and I am unsure why.

Does she have mites? Or when your are in the coop or the run are any chickens attacking her?

She is 8 months old and is on layer pellets meal worms and grass I cleaned the coop and run and dusted her and I can’t see any signs of these We have just recently lost a chicken and was wondering if they are trying to get the pecking order sorted. I will add a photo in

What is the protein on the pellets and how long has she been on them?
What did you dust her with?
