I was taking my ducks out of the tub tonight and I noticed a couple of them have little soars on the bottom of their feet. They are on straw for bedding. I was reading that a may be a dietary deficiency. What should I give them different and how much. Right now they are eating a duck and goose maintenance plus I give them peas and spinach. It looks like the picture in "Storey's Guide to Raising Ducks" on page 252. It says a diet deficient in biotin, pantothenic acid, and or riboflavin... how do I know which... and what do I give them? How much? Poor little feet.
