I am making a list of items I need to buy before I get my duckling this spring. I have a question about niacin; if I give the ducklings brewer's yeast I don't need to put niacin in their water correct? How much brewer's yeast do I need to put on their food? I will be getting 4 or 5 ducklings.
Thank you,
Loreen
