Barred Rock x Buff Orpington chick color question

[nicalandia]

Do you know of any chicken breeds that have c^re or c^a?

I thought that, practically speaking, C+ and c were the only alleles likely to be seen in a backyard flock.

Those were found on White Rocks and White Wyandottes.

Thanks! I had not realized that.

I am surprised that you did not ask what was Tyrosinase Recessive White?

I assumed it was the most common one, since it got the c with no extra letters.
Is that not the case?

Officially there are two types of recessive one, one based on the c allele(c and is Tyrosinase based) and the Tyrosinase-independent recessive white which is based on the mottling mo allele(mo^w) found on white birds from Japan.

This is a later pic of one of my white chicks from this BOxBR cross at about 5 weeks. The white chick from mom #1 appears to be a cockerel. I thought dominant white is supposed to "turn off" black? Does it leave black in some places?

I know his pose looks weird, but don't worry - he was having a nice nap on my knee. He's getting progressively more black showing up on his tail and wings, just in places where it's not obvious unless he flaps or shakes his tail. It's not a barred pattern - it's just kind of black swatches.

(Edited because I initially just said "it" without making it clear I was talking about the dominant white trait)

Dominant White is leaky, especially when a chicken has only one copy of the gene.

Examples of black leakage on chickens with Dominant White would be Paint Silkies (who often have fairly extensive black leakage), and California White laying hens (who often have small amounts of black leakage.)

I got a br rooster and bo hen chick and she/he is black with a silver face gender please

With a Barred Rock father and a Buff Orpington mother, both genders of chicks would look alike. You can only sex the chicks by color when you do the cross the other way (buff father, barred mother).

ok thank you
