So I have 4 ducks and have been trying to figure out two of their genders. I know two are males but the other two only quack when I pick them up. Otherwise they sound like the boys do. And i just got two Pekin ducks and all they do it quack. So I didn’t know why the other two only quack when I pick them up! Any one had ducks that did this? I’m really hoping they’re girls!
