Koloa (Hawaiian Duck)

I'm on the search for a hawaiian duck, not sure how many people even raise them anymore. Planning on hunting in Hawaii for all the cool upland there and it got me thinking of incorporating the three waterfowl, even though they cannot be hunted.already have the laysan, and nene in freezer tubes.
I know it's a wanted post but really figured asking here with the wealth of bird guys would be the way to go!

Thanks,

Eric
