Very pretty ducks. Doesn't look like Pansy has angel wing? hard to tell how far it's sticking out though from that angle. Only thing I can rec is when she molts out her flight feathers and they just begin to start growing back in wrap just like you would for angel wing and see if that helps. Feather could have gotten damaged at some point when growing in and next molt maybe it will work itself out. You'll just have to keep a close eye on it so if it looks like it's coming in different you can wrap. Usually only takes less than a week to fix.
