Not the best photo (sorry about that...) But i am wondering if the two Mallards i got are, in fact, Drakes. They are both starting to show an almost green hue to the tops of their noggins, and at only 5 weeks. So far, out of the 5 ducklings purchased, my Khaki Campbell is the only one quacking. The two Cayuga arent making ANY noise at all (while Im around). My khaki is most likely female, as her quack is DEFINITE. But the Mallards (Very top and very bottom in photo) have a raspy tone. *sigh* whats the chances i grabbed 1 girl and 4 boys...?
