    Quote: I Disagree, Birchen is the Second best Chick down you can work with if you are doing a Barred Sexlinked cross, Wheaten is the Worst, not Birchen Birchen chicks can look quite like Extended black chicks, so the headspot will be easier to spot, unlike wheaten here french copper maran...

    That is true if the CL is homozygous for the barring gene if you crossed a black male to that CL pullet or that CL hybrid pullet there is No Way there could be a Solid Black Rooster coming from that cross Just not possible..

    It would be Negligible and can be Mitigated by introducing unrelated ISA brown pullets to the breeding stock, what we would need to do is first establish the Silver Side of this cross, by crossing the ISA Brown Male(S/s+) of this cross to ISA Brown pullets, get that 50% Silver females and mate...
