How many generations for plumage coloration

[Fallenone05]

How many generations does it take for certain sexing factors to fade out?

I'll try to write this out so it makes sense -

Blue barred male * Blue Splash female
They made a Blue Splash Female. I'll call her BSF2.

Blue Copper Marans * BSF2
They made a Barred Blue Splash Male (BBSM)and a Solid Blue Female (SBF). BBSM was killed due to aggression. SBF is still alive and well. Deep olive egg color, feathered shanks. Combo pea/straight comb.

Blue Copper Marans * SBF. Father to daughter pairing.

Two possible chicks for offspring.

Blue chick, looks Cuckoo? Heavily feathered shanks. Looks similar to my Cochin with leg feathering, but has pea comb.

I accidentally hit post. Darn phone.

MY QUESTION
Would Barring this late in their genes still be visible on hatched males?

Does this chick look Cuckoo or are they just blue? If Cuckoo, are they potentially a male with the Barring gene?

The chick is blue. It's impossible for it to inherit barring.
It is impossible for SBF to have the barring gene because it is a dominant sex linked gene. Her mother, BSF2 had barring but it was hidden because the blue gene has a tendency to blur out barring. However, only the BSF2's sons would inherit her barring gene, not her daughters.

This is probably a silly question but how did it pass from BSF2? If they're sex linked how would her offspring be sexed via Barring? With sex links I thought it only worked the first generation.

I don't know how else to ask this either (please ask clarifying questions if I don't make sense), but Splash falls under 'solid' coloring right? Talking it out to myself it makes sense since it's an expression of two blue genes being present.

I'm sorry - I'm trying to learn. I appreciate you getting back to me!

It's my bad. I didn't explain it well. I've decided to just draw it out because I think it will make more sense.
Yes, for these intents and purposes, splash is a solid color, as in, non-barred.
However, BSF2 is secretly barred.
But she hides it well because the blue gene obscures barring. Especially two copies.
I've stripped away the blue gene to show what hides underneath in this example.

Males get two copies of the barring gene, females can only get one, because it is on the Z chromosome. The other chromosome, W, cannot have the barring gene on it.
I don't know if Blue Barred male was double or single barred so I left a question mark.
Regardless, BSF2 received a copy of barring from her father and nonbarring from her mother. You can't see that she is barred but it is clearly evident she has it because when she is bred with Blue Copper Marans male, her son gets a copy of barring from her and a copy of non barring from him. SBF gets a copy of nonbarring from her father and a W from her mother.
She has no barring because if she inherited the barred Z chromosome from her mother, she'd be male.
SBF and Blue Copper Marans both don't have barring. Therefore, it is impossible for their offspring to.

Thank you, this was fun to figure out.
