We have chicks and ducklings that are a couple weeks old. They were on a chick/duck starter grower but one of our ducks has very strong legs and the other swims fine but crawls more than walks so we want to make sure she's getting enough niacin. We found some Purina medicated chick grower food with yeast (niacin supplement listed in ingredients) and the only medication listed is amprolium. Would you add additional niacin supplements or trust that the supplement in the food is enough for the ducks?
