I agree with clm, it certainly is ideal if you are raising the duck yourself and know exactly where the meat is coming from.
Gail P, I feed raw duck but my situation is a little different than yours. Duck around here is too expensive to purchase locally (& I don't have the set up to raise them myself), so I buy it from Urban Carnivore. Comes in 8 ounce patties (includes the bones and organs). I feed it raw, just like any other meat I give. My dogs really like it, I feed it quite regularly to my dog with food allergies.
Best of luck!
