My ex got a pair of ducks and a few RIR hens... one of the ducks is a Rouen drake, of that I have no doubt. But, the other one... she is colored similar to a Rouen, but she doesn't have the speculum feathers on her wings, they're all the same color. And she's a much lighter color, more of a fawn or tan color. I should have taken a pic. The only difference I saw in build is her neck is a bit more slender than my Rouen duck's neck is, she's about the same size overall though. She's absolutely gorgeous and I'll see if I can get a pic to post here later. If anyone has any clue I'd like to know lol. I almost think she may be a hybrid of some kind.
