Dr. O,

I checked with Blackwing Farms and they said that all of their poultry are fed Corn and Soy Bean.  I was surprised too!

Ducks have a slightly higher protein diet then other birds, I will check with the nation's expert, David Holderread, from Holderread Farms in OR, for a Grain-Free diet.  I'll let you know what I find out.

Thank you!
