Then ALL of your chicks are going to have one copy of sexlink barring gene(which is good)...Good to have you back Marvin. Yes I crossed a RB rooster over HRIR hens. I have 1 chick that is very much wildtype, very pronounced. I have others that the chipmunk markings are more muted, not the black stripes but still very much visible.Should I keep those chicks as well, or just the one that is very pronounced?

keep the muted ones too, but keep an eye for that well defined chick, cull all of the wheaten looking chicks, even if you dont see the headspot at this stage(could be very faint) once you are ready to go back to Rhodebar e+/eWh B/- BC2/3 females crossed with e+/e+ B/B male this will regain the autosexing trait..
