Hey guys, forgive me if I have missed a previous thread on this. But I was wondering if we could compile a list of any good retailers (online) of niacin in the form that ducks need it. I know you can get the standard niacin capsules for humans but sure this isn't the same. Also, the quantities and how to feed it to ducks. This would be a great help . And if I have made the silly mistake of starting an old thread please be kind and redirect me. PS. I LOVE MY DUCKIES SOOOOOOO MUCH! Im so glad I found this forum as my friends and family just don't understand how amazingly amazing ducks are! Love you guys! Thanks for any help I receive.
