Calling all Marans experts - Golden cuckoo? Cockerel? 5 weeks

[Glory to His name]

And a follow-up question on genetics..
I have several black copper, several splash, and this one. I only want to keep one Marans roo. If this guy is the one, what will that look like genetically speaking with those crosses?
I’m very interested but admittedly also very unknowledgeable when it comes to breeding/genetic traits.
Am I correct that the barring gene can be used to sex chicks? If so, would that be the case with these crosses?

He looks to be a golden cuckoo Marans. The only other thing I can think of is olive egger.

He cannot be used to make black sex links. That only works with a non-barred/cuckoo male over a barred/cuckoo female.

The lightness of his color leads me to believe he is double barred, which means all of his offspring would be barred, with a single barring gene, unless the mother was also barred/cuckoo. In that cross, males would be double barred and females single barred.

That’s very helpful, thank you!
