Blue cuckoo marans/ blue copper marans

[Jvierra]

I have a blue cuckoo marans hen with blue copper marans roo? What should I expect?? An how do sex them? What kinda breed will this be?

That's a sex-link pairing. Solid pullets in black, blue or splash. Single copy barred cockerels in black, blue and splash. You will be able to sex the blues and blacks at hatch as any with a head spot will be males. You won't be able to sex the splash since you won't be able to see headspots
They will be Marans but non standard mixed varieties
