Losing feathers on one wing, not sure what to do!?

[Trwhead]

My olive egger is about a year old and has been losing / missing feathers on one wing for the last 4-6 weeks. She's acting a bit lethargic and has stopped laying eggs.

She isn't molting or being picked on, and I don't see lice or mites. No other chickens in my flock are exhibiting similar symptoms. I've been using antimicrobial spray for the last week or so with no changes. Would love any suggestions from the community on what's happening / what I'm missing / what I can do!

i’ve never seen this before but could you maybe do a flea bath to do a good check for fleas? i’ve only seen it done with kittens but dawn dishsoap ring around the neck and then submerge neck below into water the fleas will try to escape and get caught in the dawn dish soap. check the base of the wings for lice. castor oil is antibacterial and promotes hair and feather growth in almost all creatures so that might also help. do you have a rooster? some roosters have a favourite hen that they tend to peck at. do you notice any warts on her? any recent moves or changes in diet or other factors that could be causing her stress?

Great suggestions, I'll try the dish soap ring and the castor oil! I don't have a rooster, and no recent moves. I did introduce 3 new chicks to my flock (for a total of 7) about 2.5 months ago.. the olive egger is fairly hostile to the new chicks since they're still growing but there isn't back and forth pecking and they don't roost next to each other. The new chicks were isolated for a little over a month before they met the existing flock.
