Bantum all gray chicks- what are these cuties?

[TracyYoung]

I purchased 10 Bantum chickies 2 weeks ago and what was supposed to be a blue silkie looks different to me! They are all gray, slate feet and lightly feathered on the toes. Unlike their silkie sisters they have only 4 toes and their feathers are much smoother. What did we get?! Looks like tiny penguins!

What comb type? Single? Pea? And do they have beards? Considering their legs are feathered, I'd venture to guess Self Blue d'Uccles without further information. Even if not d'Uccles specifically, they're certainly Self Blue.
