Thanks D,I use the rubber feed bowls for water for my Muscovy and all I do now is take one of the pills and just drop it into the water. She finds it and gobbles it down. Niacin is a B vitamin so it's really hard to overdose your duck. I am now giving mine 1-2 of the pills a day and the improvement is marked. Hope this helps, they really do like the chance to dabble and come up with a tasty treat, lol.
