I think I have the opposite going on here. I was hoping for a male and a female, but I think the two ducks I got (just under 2 months old) are both female since they can both make pretty loud quacks. if I'm right we're going to have to find them a boyfriend, hopefully the same breed as them, which I'm not looking forward to since it was a fuss enough last year trying to find someone within an hour or so of a drive away selling young orpington hens in small numbers (we only wanted one or two, we wound up with just one to add to our existing flock of young birds, mostly silkies).
