Genetics of a cockerel

Hello all together :)!

Today i want to introduce to you one of my cockerels from this year (definitive holdback!), and i would like to ask if somebody can tell me, how his appearance is explainable.

He started out as a normal black chick with a little whitish down on his throat.
His Father is my Avatar rooster, his mother a brown red (gold birchen) het. mottled- hen.

Father is a multicross of:
- White laying hybrid
- gold spangled Owlbeard
- "black bantam hen with horn comb"
- Javanaise/ "German Bush chicken" (a very similar breed to the Javanaise, but completely different background) in gold duckwing with some sumatra blood. (mother)
- Dominant white/ recessive white (father)

Grandmother (mothers side) a cross of:
- Skansk Blomme Hona (Swedish Flower Chicken)
- Javanaise/ Bush Chicken in dominant/ rezessive white (same father as above)

Mother (gold birchen het. mottled) from this hen and Swedish Flower Mix- Rooster

The cockerel in question goes back to an old Araucana mix hen of mine, which had (very few) similar chicks before. So from hatching eggs i sent off a cockerel hatched, that looked firstly just like any cuckoo chick. But with growth, more and more solid orange came in his cuckoo color, which went so far, that the young cock became almost plain orange, with nearly no cuckoo remaining.
And as you can see in the pictures, it is nearly the same with him. With the difference him being a black chick at first, and then developing more and more of his creamy yellow color, Which is now, shortly before his full maturing, so pronounced, that only his tail remained black, with his neck feathers showing little amounts of black.

I know so far, that he contains the Ginger gene, and that this spreading color, which in the end nearly deletes any of the black ground color (except his tail) must be depending on the Owlbeard ancestor (his great great great grandfather). Maybe/surely he has some columbia or other black diluters too.
But how can this be, and work?
In his female relatives are and were few hens with similar appearances. With the difference, that the hens has this very different color just in patches. So a red hen, which had black areals in the color, and a still living great cousin, which is blue with brassy parts on the breast (she molts right now, but when she is done i can post a pic of her, too). Can that be the "female version" of his coloration?

His color development is a huge mystery to me, and i want to understand it, because i want to breed that coloration further, to become a "trademark" of my backyard mutts. Because of its huge rarity, its specialness and because it was gifted to me in a tiny little blue, hook billed, inconspicuous Araucana cross hen, and one year later a related (though not first grade) het. dominant white hen, who both gave chicks with that same color development.
I want to apologize, if my Post is a bit confusing, but i 'm not a native english speaker (german), and if you have any questions, please don't hesitate to ask :)!

Kind regards,
Andreas

I'm really not sure what you want to know. You have a cockerel that is a super mutt.
If you mate him with anything, you'll get more super mutts. You won't get a breed, you'll get things similar to any other street chickens around the globe.
When chickens run together, they breed. There is no telling what you will get. Sounds like you've been crossing breeds for a long time. Just like island street chickens.

Hy!

Hm, Genetics are always the same, no matter if mutt or not, and they follow their rules either way.

I want to know which gene causes his (and his cousins from 2013) appearance and almost completely change from a black (blue) chick to such a nearly creamy yellow (orange red) bird. That he 's not calculable as a particular breed is clear.

This nearly complete change in color must depend on one gene, and i like to know which one ;). He shows it as the only cockerel in six years now, so he must probably be homozygous for it, and it must therefore be of a recessive inheritance. But by which gene?
The two started as blue respectively black chicks, were blue (cuckoo) and black in their first plumage, and then started to change their color almost completely. That is not only because they were/ are mutts, there must be a strong gene (or genes) behind it. Just which one/s? I find their color change very unique and I know it in this form of no other breed, as even Owlbeards start with their ground color from their first plumage on...

It 's a huge mystique for me, and I had hoped that you as (even as) hobbyist much, much more experienced people in such specific issues (compared to the specific knowledge in German forums) there would have some advice for me.

Problem solved - he became a rapist, and thus he has forfeited his right to stay. Hope he is as delicious as he was nicely colored...
