I have a small flock (2 drakes, 2 ducks, need to rehome one of the drakes as they're beating up the poor girls) that are mixed Swedish. They mutter a lot, but it's low volume unless one annoys another, then the volume goes up for a couple of minutes, "blah blah quit it" and then it quiets back down. The males are dark, with white throat/chest markings, but have bright green heads and blue bands on their wings. The girls pop up into a runner stance off and on, and are tan with white. They're molting at the moment (I just got them, and between the move/change in feed, and having too many males, they've been off laying for the last 1.5 weeks... :-( ) hopefully they'll get back to business soon (I think I found a couple of shell-less egg remnants in their pen this morning, so hopefully they'll be on to laying eggs again soon). In any case, nice to meet you folks...
