So, my ducks are about 5 months old now - I was told they were both girls, but I'm starting to think otherwise. Lucy, the black magpie, doesn't like to quack, unless (s)he is really bothered by something. Her buddy the runner mix makes all the noise. I listened to some quacks online, and the male duck sounds that I heard sound a lot like my magpie. On the other hand, I've read that the males have a curly tail feather, but I don't see that on my magpie. Can anybody tell anything more from the pictures?
