BBS Genetics questions

[CG Farm]

I know the rule on breeding BBS but my question is does the rule breed true if crossing breeds? I’m wanting to add Blue and Splash Ameraucanas to my OE program. I have Blue and black copper Marans. If I breed a splash ameraucana to a blue copper Marans roo will it produce 50 blue-50 splash F1 Olive eggers?

Yes, the gene for BBS coloring is the same regardless of breed, Bl. So crossing a Blue (Bl/bl+) bird of any breed to a Splash (Bl/Bl) bird of any breed will produce 50-50 Blue and Splash in the offspring.
