Does my muscovy have angel wing?

[Tay's Ducks]

We have 3 mallards and 2 muscovy ducks who have all been fed the same kind of food since we got them when they were babies. However, our male muscovy (his name is Otis) has a right wing that has always stuck out ever since his feathers came in. We thought it was funny and just how it was; however, we just discovered what angel wing is and think he might have it. What do you think? I have inserted pictures with this post. Should we do anything about it? Is it too late? He is about 4 months old. He can fly somewhat (not nearly as good as our female Muscovy who has normal wings, though). I read angel wing can lead to early death. I am concerned for Otis.

It does look like a slight case of angel wing, but I doubt that it will have any impact on his lifespan.
