Okay, I did mention that I'm a complete newbie when it comes to ducks. I have two and I'm not really sure how old they are, though they're just really starting to get feathered out now. I posted pics here and was told that I probably have a Khaki Campbell and a domestic Mallard. I've been tryin' to figure out if I have a female Mallard... can't tell by the quack as I have nothing to compare it to. But... "she" has an ever so slightly greenish iridescence to "her" head. Am I looking at the early sign of a drake, or do the females have any hint of green on their heads? Yes, I guess I'm a bit impatient to know.... Thanks for your help!
