Do my older ducks need supplemental niacin? Approx 1 year old. Do my young ducks need supplemental niacin? Approx 11 weeks old. They are fed an all flock pellet, 20%. To also consider: one of the younger ducks seems to have some leg struggles. Nothing I can outright pinpoint, just waddles a little funnier, runs much slower, trips more than the other youngster. Wondering if youngster needs a tad more niacin. If they do need niacin... Today I went out with some peas. Youngsters were way more intrigued but everyone got some. Is simply adding peas to their feed enough of a supplement? Seems the simplest option, grocery store always has peas! Looked on Amazon for niacin, yeast, etc. Some of the best deals had confusing info. Such as, manufacturer stating "no B vitamins in product" but a screenshot of label said "niacin 30%" DV. Umh...niacin is a B vitamin last time I knew. Went to both local feed store and Tractor Supply. TS employees had no clue what I was talking about. Did not appear, in any aisle, to have anything labeled niacin, B supplement, yeast, etc. They said no one has ever asked for such a thing. What do you buy?
