Here are their baby pictures that brown one was Rouen and looks that as adult. The other two drakes look like mine and the female is blue. All females I have from this pairing have been blue. These two drakes are the exception.
Yes I'm sure I got these eggs from @Texag87 who only has one drake, a fawn and white runner. You can see it in his avatar. I'm pretty sure these are pekin eggs, they are big birds. All the birds but these two drakes are blue. I was surprised to get the colors in the two drakes. Could it...
His dad is a fawn and white runner and his mom is Pekin. I think he is gorgeous. He has a brother I rehomed that looks just like him. All the other ducks I got from this combo are blue.
