Agreed. To treat AW, you'll need to wrap the wing. You will be able to figure out if it's wing feathers or not while doing this. I'll find a wrapping for AW thread for you. Give me a second to look through my bookmarked threads.
How long have you been seeing this? Like mentioned above, AW usually starts whenever the heavy flight feathers come in.
