It actually doesn't have enough of everything needed to balance the nutrition needed for Ducklings...Chick feed does not have enough niacin for ducks, and some ducks require more niacin that's in Flock Raiser or other all flock feeds.

Exactly...Now Niacin can be fed in many other forms of feed and not needed in the form of brewers yeast. Proper feed from the start is needed. All I'm saying.
Bottom line is Ducklings require a special balance in nutrition..
Amen!!!!!I use Nutritional yeast for my self and my flock it's a really good natural way to get the B vitamins essential for a healthy body. I am not saying every one should do this but gosh we have so many members coming back and saying how the niacin helped their little duckling recover I don't even know why there is a negative review of this.

My ducks are full grown and have never ever had a niacin deficiency cuz I gave them Brewers yeast(another form of niacin). I still give it to mine and they have such fast little legs(you should have seen them when I gave them meal worms today). I say, cuz I am giving them chicken feed, to give them brewers yeast just as an added supplement. Also the brewers yeast that I buy has garlic in it and o my goodness garlic is one of the best supplements for ducks. Here you guys can check out an article of mine for some supplements I give my ducks. https://www.backyardchickens.com/forums/ducks.42/ Scroll down and you will find supplements there.
