Yes the mallard colored runners are called mallard runners I believe, I think that's what Miller means.
They're supposed to be all runners, I'll know for sure in a day or two when their legs get a bit stronger.
If this one's not fawn and white, then I don't think I have any. The 2 yellow ones I have don't have any tiny brown patches the fawn and whites're supposed to have.
edit: OK just saw Hillbilly's post. I may still have 1-2 fawn and whites then. I hope they are, that's the color I want the most!
