Hi everybody! I'm quite new to having ducks and I've had my 2 ducks for about 16 weeks now. I really would like to know for sure their gender. I've looked up how to sex ducks by their "quack" and from what I can tell, my Black Swedish, Quackers, sounds like a female and my KC, Phelps, sounds like a male (though I thought KC drakes had the green head?). Please help!
