Nutrena feed should have enough niacin for ducks. It's what I use and I've not had a problem.
That said, Pekin ducks are more prone to deficiency.
If he's still that way in the morning it won't hurt to try giving some vitiman B and see if it helps.
Also pick him up and check the bottoms of his feet for anything that could be wrong there causing him to stumble around.
