Baby Wood Ducks

I've got two tiny (palm-sized) little babies I rescued when their mother was hit by a car yesterday. I have raised two ducks of my own (a mallard and a reun (sp?)) so I'm used to the baby duck routine (brooder, baby mash, etc) Has anyone had luck with raising wild babies? My father is a wildlife rehabilitator, but he's never had ducks. He assures me they should be no problem, but I'd like to hear from people who've been thru it themselves..
