Is the wing dragging a little, or not quite in position? If so, it is possibly broken, or at least badly strained.
Stretch the wing out completely (while holding her firmly so she doesn't hurt herself fighting you) and feel along its length. Check for swelling, abnormal warmth, and weird direction. Also feel the joint for the same things. Compare with her other wing, if you're not sure.
If you feel anything, gently make sure that the bone doesn't bend or shift. If it does, you could set it (pull completely straight and feel around the break, still pulling, until you know it's straight) but it isn't absolutely necessary.
Then bandage the wing together, (forearm to upper arm, if that makes sense) and tuck it against her body with a second bandage so that it's completely immobilised. You can use masking tape. and there's no need to bind the other wing.
Her shoulder might be dislocated. You would feel swelling at the joint. Again, pull straight and then tuck and immobilise (I don't know the exact motions for this one. I've only ever dealt with broken wings.)
If you feel no breaks or dislocations, then it's probably just strained. Just immobilise it and let her heal.
Also, I'd provide a nutrient supplement, simply because I believe in ruling out all problems at once.
