Goose makes good Jerky. I'm not partial to the "fishy" taste of wild duck and it will still come through after making jerky. If you like that flavor than this will work.
Take your Goose or Duck and breast them out. Use an electric Knife to make about 1/8 " thick Jerky strips, or 1/16" if you like them thinner and crispy.
I use Hi Country Jerky Cure and Seasoning. I can find it at the local supercenter here, but Cabela's, Bass Pro and other outdoor stores probably carry it. I prefer the original pepper flavor, although they have a few others, barbeque, mesquite etc.
It's helpful to have a Jerky Rack, which allows the air to flow around and through the meat. But Bread cooling racks work fine as well.
The cure will work to tenderize the meat and work the flavoring in. From there just follow the instructions on the packaging. I hand rub the mixture of cure and pepper into the meat and wrap in plastic wrap tightly and place in the fridge for at least 24 hours.
From there I always preheat the oven to 250 degrees for 20 minutes, (220 will kill any of the nasties that linger in meat, but I play it safe because of temp differences in ovens) After 20 minutes adjust the temperature to it's lowest setting and check on the jerky about every 30 minutes until it's done the way you like. About 2 hours for more tender about 3.5-4 hrs for crispier jerky.
