I have a 14 year old duck I took on with severe, long-term leg deformity. I was thinking about ways to get some niacin into her as she doesn't eat a lot. Do you think it would be okay to mix up a small amount of brewers yeast in some water and syringe it straight into her mouth? Or would it be better to crush up a tablet and mix with water and administer in a similar way? Thank you! Faith
