Or a legbar rooster over dark egg laying welsummer.You know how cool are Autosexing blue egg layers like the Cream Legbar ares? Well I think it would be even cooler if one would start a "Autosexing Olive Egger" breed..
And it would not be hard at all, just get yourself a few Black Copper Marans, a Cream Legbar rooster and breed back to BCM to get back body and type while keeping sex linked barring, then it would be a matter of making homozygous barred cockerels...
The other way would be to breed Golden Cuckoo Marans breed to Legbar or Ameraucana..![]()
F1 pullets would be autosexing. Cockerels would need the second barring gene so breed pullet back to CCL.
Then its just a matter of keeping the egg color which is standard issue with OEs.
