Does anyone have any of the White Layer Ducks from Metzer Farm? Are they calm and friendly? Are they extremely loud or more on the quiet side? I like the look of the Pekins but they are to loud for my backyard flock from what I've read. I'm planning on a couple of Welsh Harlequins and maybe a couple of these. I will have to get females because they will free range with my 10 hens during the day, they will have separate coops for night.
