First off the flight feathers need to grow out...Then if it actually is Angel wing you will have something to actually wrap....I understand your worried....Although I honestly think it's just the feathers growing....
They will grow out sooner than that...Two weeks and the flight feathers should be grown out....They appear to be growing out rapidly from the pictures you posted...The extra weight and the prickly feeling is uncomfortable
Give the wings time to grow out....If they still tip outwards then try wrapping...A friend of mine that I sold some Call Ducklings was positive her Ducklings had angel wing...Nope, as I said it was the flight feathers growing out...Ducks are great....
When the flight feathers grow out they can appear pretty wonky and the Ducks will hold the wings away from their body....I would wait a couple of weeks....
