Have you tried posting in Buy/Sell/Trade? I found my duck pretty quickly by posting in there. I'm in Maryland (Hi Neighbor) and only had one duckling hatch. I needed a companion for my duck. Posted in there, got a response and was able to get a really nice quality duck. I got a white call and she's just beautiful!
I posted in another thread about some domestic ducks I saw at a park when I was down there (I live in ME). There was a pair of gorgeous ducks, though one looked like it had angel wing or a broken wing. Anyway, these ducks were obviously dumped there. I am waiting to see if the other thread has info about them being rescued. Sure hope they get taken out of there, I am really sure they were Easter ducks that some %(^*#@(% dropped off at the local pond.
