If a BSL is a cross between an RIR rooster and a barred rock hen, how does it come out mostly black? And how would you get a BSL that is also an EE?

Barred rock hens only carry 1 copy of the barring gene and pass it on to male chicks, Barred rock roos are HZ for barring and pass it on to males and females. Barred rocks are a black based chicken and black is passed on to all genders.

Because a Barred Rock is techinically a black bird with white barring whan you cross the red and black the black is the dominant color and cover most if not all the red on the female offspring the males will be black with barring and some red or straw color leakage in various parts of the plumage.

You can make a BSL EE you need a Red(gold gene) male and a Barred female to do it. Still works the same as RIR x BR as its not the breeds that make the sex-link its the color combos of their genetic makeups.
