Ducks are very good eating, at least the puddlers and vegetarian divers like redheads and cans.
I don't like cooking and can't be bothered with fancy recipes, though I'm sure they're very good that way. I simply breast out the duck, put it in a ziplock with some italian salad dressing for 10-15 minutes, and then put it on the grill. The same rules apply for duck as for venison - don't cook it well done. I think ducks are wonderful this way.
Geese are another story.
