Lameness in My Crested Duck

[Ravynscroft]

Not that I can see/have seen.. that's very strange though.  Glad that she's back chasing frogs again!

I'm hoping that some supplements and physical separation (although she can still see the rest of her friends) will do the trick.  Anyone have any suggestions on where to get Brewers yeast?
