Hopefully a challenge!

This one just popped out. Same feather color as the others (silver version), but white, non feathered shanks.

Edit: opposed to the black feathered shanks from all the others who have hatched.

 

[NatJ]

Hatched a silver version this morning. Attributes look identical at the moment to the gold. We've got a few more golds too. All look to be the same

Which cross is this from?

I thought the one in the first post was from red rooster x gold hen, which is not going to produce any silver chicks, so this one must be from a different cross.

We have a silver and a gold seabright hen, and the rooster is a red Cochin frizzle.

Correction - this one has GOLD FEATHERED white shanks.

We've hatched 7 total now, all have some sort of feathered shanks and similar patterns in terms that initial feathering, aside from the colors.

And last for the day was a Mille flure hen v self blue roo D'Uccle. Obviously really difficult to tell feathering when they are 30 seconds out of the egg, but looks like an SB

@NatJ I really don't understand the SB genes, but is there a chance this cross can result in an SB with the MF patterning?

Side note : we just got this Keebonix 12 egg bator just for fun little hatches like this, but i was super impressed with it. 100% hatch rate.

That means any silver chicks are cockerels, and have the silver hen as their mother.

Daughters will be gold no matter which mother they have, but they might be different shades of gold (darker or lighter or redder or yellower or something like that.)

Probably black.

No and yes.

In a first generation cross of Self Blue d'Uccle rooster and Mille Fleur d'Uccle hen, assuming that each is from a line that breeds true for their own color, there is no chance of getting a self blue with mille fleur patterning.

"Self Blue" is caused by the recessive lavender gene, which dilutes both black and gold shades.

A "Self Blue" chicken is genetically a black chicken with two copies of the lavender gene.

A "Porcelain" d'Uccle is genetically a Mille Fleur chicken with two copies of the lavender gene.

From your first generation cross (F1), you should get black chicks, maybe with some amount of leakage. They will carry at least three recessive genes: lavender, mottling, and whatever base color the Mille Fleurs have (probably wheaten).

If you breed those chicks back to the self blue, you will get about 50% black chicks and 50% lavender (self blue) chicks. The other recessive genes will be present in some of the chicks but not visible in any of them.

Or if you breed the F1 chicks back to Mille Fleur, you will get four main colors of chicks:
25% black
25% mottled (black with white mottling)
25% mille fleur
25% buff columbian (=mille fleur but without the mottling)
About half of those chicks will carry the lavender gene, but none will show it.
The self blue rooster may have the silver gene, in which case the "mille fleur" and the "buff columbian" will actually be split among ones with gold, and ones with silver (silver mille fleur, silver columbian).

Or if you breed the F1 chicks to each other, you will get quite a rainbow of colors, including everything listed above plus:
lavender mottled
porcelain (=lavender mille fleur)
lavender buff columbian

and if the self blue rooster did give silver, you will also see:
lavender silver mille fleur
lavender silver columbian

So the self blue with mille fleur patterning (Porcelain) can show up in the F2 generation (from crossing two F1 chicks), but you will have to hatch a lot of chicks. They will be one of the rarer colors, probably about 1 or 2 per hundred chicks. (If you keep the lavender mottled, the Mille Fleur, and the lavender buff columbian, you can cross them with the F1s or with each other and have a better chance of getting porcelain in the next generation yet.)

Ok - here is the D'Uccle baby. Looks blue? Not self blue, but blue.

He or she is soooo. CUTE!!!!

Thank you.

SHE () is a looker, that is for sure.

I see why you say that.

Actual blue is caused by one gene, and lavender is a different gene.
"Self Blue" usually means the lavender gene.

If the chick is blue, that means at least one parent must have the blue gene.
So either the chick is not really blue, but just looks it.
Or the color of your rooster could be mis-identified (he might actually be blue).
Or the rooster could possibly have both genes, lavender and blue. Many people try to keep them separate, but some people do mix them.

Also, if the "self blue" rooster was the father, I now know he is NOT pure for the gene Extended Black-- because that chick is not showing Extended Black coloring! So at least some of my predictions were wrong, because I was starting with "if he is pure for...."

At present, I'm going to wait for the chick to grow some more, before I make more guesses.

Would this mean that he is not actually D'Uccle? Here is the pair.
