I bought fingers marked specifically for ducks. I tried a couple of chicken fingers and they tore the skin even if I cut them in half lengthwise. The duck fingers are short and very soft and flexible.
Wet ducks are fine, they actually make less of a mess. I pluck and then take the shop vac for a little clean up of the few feathers that get away. It makes less of a mess than hand plucking but a bit more than if you just rip the breast meat out without any plucking.
