Possible angel wing?

[J99]

I have a Rowen young duck and I noticed the other day a feather sticking out of his wing , well it’s stayed like that now
I’ve seen him open up his wings while swimming and they look ok but this always sticks out when he puts them back down
Do you think his wing is broken? And if so what do I do about it?

That is angel wing and needs to be wrapped asap.
