Feed Options for Ducklings

[Gallosaurus Pex]

Hello all, I'm new to ducklings and I wanted to see if anyone has any feed suggestions. I've used DuMour starter/grower for chicks in the past, and I've heard that it has enough niacin for ducklings, but I want to make sure before I make any decisions. Can anyone who has used this feed confirm? I will, of course, have Brewer's yeast on hand in case I need to supplement the feed.
I've also heard good things about Mile Four feed online and was wondering if anyone has tried that or knows of cheaper organic options.

I've used that in the past, given its for chickens I would still provide extra niacin in a form of either brewer's yeast or a poultry vitamin.

I use Mazuri waterfowl starter. It's pricey but much better smelling poo. Lots here use flock Raiser crumbles and are very happy with them.

My ducks eat New Country Organics and it's priced pretty reasonably (for organic at least ). The duck starter is $36.50 for 50lbs and the grower is a little less than that. I also ferment mine which seems to make it last a little longer.
