I'm a new duck-keeper and I have 7, 5 week old ducklings. Now they're starting to get adult feathers, one appears to be growing a wing at an angle. Is this angel wing? And if so, what should I do?
Possibly or they are just holding the wing out because the wing feathers are prickly.. wait a bit longer before treatment because the feathers need to grow out a bit more.
Very good chance that is angel wing, so if I were you I would read the links that @Soon2BChixMom posted, choose a wrapping mehod and wrap your ducklings wing. Wrapping it now before it gets worse would be best, IMO.
