I have 3 ducks a Pekin, a Swedish Blue and one that I have no idea what it is! It looks like a Pekin but much smaller, feet and bill are very pale almost pink and a few black spots on its head. And it is older than my other two. They are all around 7- 8 weeks now. Could this be crossbred somehow and is that even possible? Any suggestions would be so appreciated! Thank you!
