Most of the duck jerky that I make is teriyaki some with random marinades the at I cook up that I never remember what I put in them. It's pretty easy. Breast the ducks place in a container of water with some salt. Let it sit in the fridge for 2-3days changing the water every day to get all the blood out. Slice thin and cover with teriyaki (I prefer soy vet teriyaki) let sit another day or to a different pat dry with towels and dehydrate for about 5-7 hr depending on how you like it. I have to hide it from my wife or I wouldn't ever get any haha.
