Well, I've had ducks for 3 years now, and until a little while ago, had never heard of ducks needing niacin......I've done so much research and reading on ducks before and since I've had them that I'm really kicking myself for missing this crucial detail.
The only thing is, I was reading about it on the Metzer website (http://metzerfarms.blogspot.com/2011/03/are-my-ducklings-leg-problems-due-to.html) and my ducks don't have any of the problems that a niacin deficiency causes according to them.....They're lively and happy......Do they pick it up foraging? Since they seem healthy, does that mean they're getting it somewhere else and I don't need to give them any extra? Or should I still start providing them with it?
Thank you!

Thank you!
