This push for niacin is not a cure...Ducks actually need more minerals and vitamins in feed so in many cases niacin is not going to cure the Duck so I wish people would stop running to that as a cause..Older Ducks generally never suffer niacin deficiency...Ducklings up to 3 weeks are in more danger...
