yes...that is definitely true.

but what I was(trying to say, maybe not entirely making sense, though, (LOL) is the gene dilutes almost all the brown/gold/red tones on the males but leaves some coming though on the females. so you get a Roo that is stark white and black and a hen that has some red showing through, expecially on her breast, so it doesn't dilute out all color on the girls.

I guess I thought that that was why the boys seemed to be diluted more, even as chicks.

I go by the shape of the markings more than color...  the pullets tend to have a wider V with more defined edges while the roos tend to be a bit narrower, and/or the edges aren't very well defined and look kind of jagged.  i do agree tho, the one above does look like a pullet.

this has followed true for me for all my dorkings, sg red and colored, but not for crosses with other breeds.

Ki4got... Can I try and take a good picture of the new chicks for your advice on gender... I'm all over the board on what I think I have...

the Salmon Breast is independant of Silver or gold.

silver affects red pigmentation everywhere BUT the breast... in the roos, it's black either way you go, in the hens the salmon breast will be a bit darker in reds than in silvers, but it's still there.
The salmon breast coloration is dependent on the e-locus genes... in this case, e+ (the wild type)

why do they call it "sex-linked silver" then? I guess I am confused.
I was told that the doubling of the gene on the males doubled the effect of the gene...
because the (S) gene was cumulative.

Quote: it's an incompletely dominant gene, so you do have a stacking effect in the roosters, but it's sex-linked, because it's located on the sex chromosomes. the rooster has 2 (S/S), but the hen only has 1 copy (S/-) because the - is the designator that tells the egg to be girl or boy. kind of like in people, men are XY, women are XX. in birds it's opposite for sex, but only the X can carry any color genes. the Y or - is the sex determiner part of the gene.

Gotcha...so I guess what I was thinking about was the stacking effect in the males...so the incomplete dominance thing.
because the male has two copies it is stronger in the male, hence the male chicks have diluted coloration.

Hello to all
I was wondering if you would know any one that ships day old silver gray dorkings chicks.Thank you
