Silkie genetics, what can I expect from this batch of eggs?

[sljack2006]

I am expecting 12 eggs from a chocolate roo over 3 black and 1 chocolate hen. I lack in genetics knowledge so was wondering what color ratio you all thought I might end up with? Thank you very much.

Chocolate x Chocolate = 100% Chocolate

Chocolate x Black = 100% Black (?)

Not sure on the second cross, but black will definitely be a predominant color.
