I don’t add niacin/Brewer’s Yeast to the whole feed. I only add when I’m filling the feeder for my Pekin Ducks. I do 2 TBSP Brewer’s Yeast per 1 cup of feed. My ducks seem to be fine at 3.5 weeks old.Yes I have four 2 weeks old Pekins. So I should add in nutritional yeast to this brand? Do you buy chance know how much I should add to a 50lb bag?
