Thanks for the 'Mom' info. I'll be looking around for Mom material during the next few days based on what I read here. I figure I get plenty of eggs from my Runners so to get a couple of ducks who don't lay much but are reportedly good Moms would be worthwhile. I'd love a Muscovy but placing 2 large ducks in with my little Runners seems risky. I'm thinking Cayuga, Mallard, Call or Welsh Harlequin might be better. More research for now.
