Is this possible?

I have chicks hatching in the incubator right now.

I marked one of the eggs as having come from my black sex link. The rooster involved had to be either a RIR or a RIRxBO.

I just watched the chick hatch, and it is completely blonde!

Is this possible? Did i just mark it wrong?

Since a Black Sex Link is a cross between a RIR roo and a BR hen, I guess the chicks could turn out to be yellow if they inherit that gene from both parents.
