Hi all! This is my second year raising ducks. I know that pekin ducks require much more niacin in their diet due to their size and weight. I have always supplemented niacin with all of my flock food through brewers yeast. My 1.5 year old ducks have never had leg issues. This year, I purchased two ducklings to brood with my youngest duckling. The two that I bought, both seem to have had a niacin deficiency from the start. The male has significant bowing in his legs, while the female has weakness. I have been using the added brewer’s yeast to their food, but it has only been a couple of weeks. Would it be wise to buy niacin pills and add the powder to their water or food to see improvement more quickly?
