What color are my cochins be when they get older?

[katlynd003]

I bought some Cochin chicks and I am new to the breed. I know they are black but I wasn't sure if they are gonna turn out all black when they get older, based on the pictures below.

Thanks in advance!

They could be black, or they could end up with more of a 'birchen' patterning.
