I've never tried it personally, nor know anyone who has. I do duckhunt however...
I can't tell you much about geese because they don't wonder this far down to me.
The ducks, for the most part won't have the "bulky-ness" for a lack of a better word, to use as fletching in my opinion. The speculum will be thin.
Maybe your larger divers like reds, cans, even big mallards, spoonies, etc.
Its no doubt worth a try, but I foresee the feathers being to thin and too flexible.
Granted I know little when it comes to arrow building, so take this with a grain of salt. Maybe someone more knowledge on the matter will add/take away from what I've said
Good luck!
