We have had pekins before and these look just like them except for a tinge of gray down their backs. (it is hard to see the gray on them in the picture - the one in the bottom right you can see it a little). I can't find any other breed that they resemble. What do you all think?
I'm guessing Pekin. Maybe with some odd genes mixed in, but I'm no duck expert. It could turn into something completely different. (I heard of someone who bought a flock of Leghorn chicks, and one had a bit of black on it's wing and actually was a Buff Brahma.) So, you never know.
That's what I'm thinking (pekin with odd genes) - we bought them as pekins, but we've had pekins before and never had any gray or other colors that they were tipped with. We've had surprise chicks too - it will be fun waiting to see how they turn out.
