What do you when you cross a Buff cochin hen and a Blue cochin rooster

[augustinao27]

I just had the chicks hatch and four hatched out looking blue and three hatched out buff brown and blue? what are the buff/multicolored ones going to be?

IF you use a genetic calculator you would get 50/50 Black/Blue, but that doesnt mean that one of the parent's isn't 100% Blue, she could LOOK blue but have another genetic color that shows through in the chicks.
