I have Biele roo x Black sex link hens. All resulting chicks have head spots, but I think BSL use Barred Rocks, right. So wouldn't all of the offspring have barring regardless of gender?
Would the irreg shaped headspots = males?
Now they are 1 week old & getting wings - mostly black with very faint barring. Shouldn't some be lighter / have more white = the males ???
Has anyone tried this combo or another barred breed with a Biele? What were the results?
I hatched blue isbar eggs crossed with my Bielefelder roo, two barred girls with a bit of gold leakage at the neck and one gorgeous blue with gold at her neck, she looks like a blue copper marans without the feathered legs.
