The backstory: I had a white Pekin drake ("Poncho") who was absolutely obsessed with one of our lady ducks (possibly a dwarf Rouen?) named Banty Duck. It wasn't mutual, and when he pulled out a patch of feathers on her back, we had to separate him. After a couple of months, he showed us once again that he couldn't leave her alone for even a moment, so we found another home for him. However, before he left, we took Banty Duck out of the pen and let Poncho mate with whichever of the other girls would allow it. That turned out to be a Khaki Campbell named Penny. We saved the next couple of days' eggs and put them under a broody chicken. Eventually, one of them turned out to be fertile. It finally hatched an extremely cute (but bizarre) little black and yellow duckling. In case you can't tell from the picture, both wing tips are yellow. At first, I was just kind of bemused. "Huh. Weird... A white duck and a light brown duck made a black and yellow duck. Cute, though." Fast-forward to today. I got my new ducklings from Metzer, including a couple of Black Swedish girls. They look EXACTLY the same as this Pekin-KC mix! How is this possible? It isn't as though I had anything with even a trace of Swedish duck. I had a white Pekin, a Khaki Campbell drake (kept separate from the girls at the time), a Khaki Campbell female, and an off-white female of unknown heritage (but she wouldn't have anything to do with Poncho, and I watched them for the whole 15-20 minutes he was in the pen). SUMMARY: It's a white Pekin - Khaki Campbell mix, and it looks absolutely identical to the Black Swedish ducklings we got in the mail today. Here are some more recent pictures, in case they help: The two chicks in the last picture are his "peeps." He was hatched under a broody chicken, after all, so now he (or maybe "she") identifies as a chicken. Thanks in advance for your input.
