Black To White Experiment

[MysteryChicken]

Oh I wasnt suggesting that, I was just commenting that it always throws me off!
Sounds like there were no other roos around then. So perhaps the prohibitive protien. The barring gene itself is actually lighter stripes of the dominant color correct? So a dark Grey with barring actually has dark grey/black as the dominant color, with the barring gene overlaid on top, the same with your Domino Roo, his red and black and blue on the wings is overlaid with the barring pattern, so she (you odd all black/blue no barring hen) could have inherited the blue and black parts from them and then a "Stop" Order for the barring, which she would then be a carrier for both the stop order and the barring. I'm not sure how you would go about getting the stop order out of there, although breeding to ones who for sure don't have it (complete barring) should surely only help?

Oh, okay. My brain is tired today.
This explains it better then I can right now.

The evolution of Sex-linked barring alleles in chickens involves both regulatory and coding changes in CDKN2A - PMC https://share.google/95Befv1zgPkzXRESj

This article suggests it's due to a full 4 genes, so potentially just one being "turned off" or "fixed" could result in no barring. (Although I should probably read it through all the way, just trying to guve you new sources of info). Since the original Cuckoo EE had the white wing tips it's possible she already had something like this going on.

At least the half lower portion of her wing feathers were white. Not really the tips.

They get random rusty ready feathers as well that pop up from time to time. That's one other thing I'm trying to figure out.

Oh i thought it was just the final pinion! Well that plus that 3 of her offspring are somehow not barred color changers... she is definitely carrying something! Is it also her/her chicks that have the rust? Or is that from others? I would think Domino could cause the rust, but I don't know the specifics of that, just that it would match his colors.

The barring gene makes white stripes across whatever other color the feathers would normally be. I can't tell if that is what you are saying or not.

Since barring is a lack of pigment, to "stop" the barring would mean to have the pigment be produced as normal, instead of interrupted to leave white areas.

She, & her daughter. It comes, & goes. Her daughter is solid black. But not anymore actually. She decided to blend with the snow this year.
Both mother, & daughter are gold based, no leakage on the mother, but her daughter has leakage in her hackles, which is a mahogany color, not rust.
The mother has a random rusty feather on her breast currently. I'll try to get a picture tomorrow.

Here's her daughter last year before winter.

I think they meant something else by Stop, but would have to ask to be sure.
