Thanks for the info Joyfullkeeper. I picked up Brewers Yeast last night and have been mixing it in the food. If there is no change by tomorrow I'll add the Niacin in the water too. I'm currently putting Apple Cider vinegar in the water because in a moment of distraction (on my part) my poodle nipped one of the ducks bills when she stuck it out of her brooder.
I feel terrible!!! I read that ACV is good for killing some of the bacteria. She is eating and drinking (I wet the food) so I'm hoping she'll be okay.
Now I have a duck with leg problems and a duck with wounded bill.
My poor babies!
