I'm pretty new to ducks and have 11 (Welsh Harlequins and Cayugas) which are about 3 months old at this point. I know that ducklings need more niacin than chicks. but I can't find anything conclusive on whether that is the same for adult ducks. When they were young I would add niacin tablets to their water. Now they are mostly free range and hang out in the stream all the time. I tried brewer's yeast with their feed but it seemed so powdery that they didn't actually consume much of it. Anyway, do they even need extra niacin at this age? Maybe they get what they need from foraging...
I believe niacin is mostly for development. If you start hatching, or allowing any of your ducks to hatch eggs, and you notice a problem with ducklings having problems with their legs or wry neck, then it might be good to add niacin into the mother's diet. Otherwise, the adults usually do fine without it...

I've never raised chicks from my birds so guess thats why they never needed it.
Scratch & Peck Feeds wrote: Niacin supplementation is important during the starter/grower phases, but not required once they begin laying eggs. 27 mg of niacin is recommended until maturity at which point it lowers to 20 mg. Our feeds contain 22.5 mg of niacin. You can supplement by adding brewer’s yeast to their feed for an excellent source of niacin. One tablespoon of yeast contains approximately 5 mg of niacin.
They now just add in the niacin because chicks (who don't need as much) just flush out the rest.
A few of our ducklings had wry neck and we tried the brewers yeats but found vegemite or marmite was easier to spread on a tidbit of lettuce or bread, far easier than the brewers yeast. Vegemite comes in a tube now so it's very convenient. I've never given any added nitrates to adult ducks.
