My DH brought me home 13 new ducklings. They are yellow underneath with black or muddy brown on top, and they all have "eyeliner". Anyone know what they could be? I can't post pics. Four have the black, the rest are the muddy brown. I'm hoping the black are drakes. Also the darker color extends to the legs on a few of them, but their feet are yellow, and so are the beaks. Thanks if you can help!
