Meats have the largest amounts of niacin, so for ducks that means insects, worms, snails, slugs, small fish, etc. Niacin can also be found in plant material but not as concentrated as in animal sources: wheat, rice, potato skins.ypically the pills contain 500 mgs of niacin per tablet. Assuming a duck is eating about .35 lbs per day (this is how much a Pekin is eating at about 3 -4 weeks of age) , they need 10 milligrams (mgs) of niacin a day. So, theoretically, one pill has enough niacin for 50 ducks.
