I really would like to start giving my ducks a niacin supplement to prevent leg issues. I got them on thursday, so I hope it's not too late to start giving them niacin. And btw they don't have any leg problems as of right now. But how do I find non flush free niacin? I looked at walgreens and they had time release niacin, but it said nothing about it being flush free. Is this what I should be looking for? If you can please include a link of the niacin I would add to their water. Thank you very much!
