For more info go to a search engine and type in duck hunting; try a number of search engines and you should get a number of sites.
Re: skinning or plucking; everybody should pluck a duck or goose at least once. The reference above has good advice. Another way to pluck is to boil a mixture of dish washing soap and water, then dip the birds. I've been told plucking after is easy. Personally I skin the breasts and legs.
I don't believe in hanging birds for days. I try to skin after one night. BTW try not to shoot any fish eating ducks; they taste really strong and might turn your family off ducks.
Good luck with your waterfowling!
