niacin for my ducks?

[theduckgirl4110]

I have a four month old khaki campbell duck. Am I supposed to be giving her niacin every day in her water? Also, I'm getting two more ducklings from metzer and am I supposed to give them niacin every day even if their healthy and dont NEED it? Thank you.

My KCS are a little over 4 months old. I stopped giving them regular niacin a month ago. I put it in every once in a while but they're fully grown.
For the ducklings definitely give them niacin in their water every time you change it. They need it to develop strong legs.
