Niacin water solution recipe?

[Sparty75]

Hi there!

We are expecting ducklings soon! When we raised some a few years ago we used a recipe that was posted on here using Durvet Vitamins & Electrolytes powder mix with water to help with any niacin deficiency. Does anyone happen to have that? Thank you!!!!
