If you use a Cuckoo with her, you will get mixed chicks. If you use a Black Copper, you will get all Blue/Blue Coppers. If you use a Splash, you will get all Splash chicks. If you use a Blue or Blue Copper, you will get about half and half Splash and Blue/Blue Coppers.My daughter and I are also looking for a Marans 'fella' for her this spring!
What would happen if we bought a Cuckoo Marans for her? We may have the opportunity to get one locally soon.
All of this is based on our experiences. None of the percentages are intended to be exact. There are always things that can and will mess up the norm.
