5 weeks ago we drove down to Metzer Farm to pick up 2 Cayuga and 3 Rouen day-old ducklings. We paid the extra to make sure we got one Rouen drake and the balance all hens. I realize it's early, but I am worried that all of our Rouens are hens. They are changing color, but they all the Rouens still look identical. They all have an unbroken black stripe down the back of their necks, no sign of a light band on any of them. I think I read somewhere that it can take month's to know for sure. It's also too soon to judge them by their quacks, as their voices are still changing. I have no experience with Rouens, our last ducks were Cayugas and a Welsh Harlequin. I am really looking forward to having a handsome Rouen drake, and look anxiously for signs that we actually have one.
