OK.. Maybe this is a crazy question, but you never know till you ask so here it goes. A Black Sex Link (Black Star) is by the hatcheries terms , a RRI Rooster and BRock Hen, right? So if you want to take a Black star hen and breed them for babbies , what exactally would I breed her with to get the true Black Star since she herself is from a RIR and a B Rock ? Would we breed her back into a BRock or the RIR or neither? Thanks for answers..
