Help 4 week old vibrating duck is that normal

[mommaundertaker]

We are new to raising ducks we have two Pekins and one that is a deep chocolate color that we are not sure if it is a runner. The dark ducking has started vibrating one of its legs. It is acting normally otherwise. We give the ducks brewers yeast. Should do something else?

Sounds like niacin deficiency how much brewers yeast are you giving?

Yeah im thinking he isnt getting enough maybe. I had one with shakey legs last spring. And i upped the yeast and he improved with in a few days
I started wetting my food so that the yeast gets eaten better .
Because the last week or so since i started feeding pellets instead of crumble the feed is gone and the yeast is left at the bottom of the bowl.
I give 1 tablespoon per cup of feed.
And just today started feeding it wet and i put 2 capfulls of organic apple cider vinegar in the feed bowl to keep it from spoiling .
They seem to love it.
