Father black skinned, mother white skinned with slate legs.

I'm not sure how that works-- doesn't the leg color match the skin color?

If the mother has the sexlinked gene for light skin, then the son must have it too.
Or, if both parents have the sexlinked genes for dark skin, then all their chicks must have dark skin too.

Your chickens keep confusing me-- I think I know how this stuff works, and then you post another one that seems like an exception!

I haven't yet seen a chicken with slate skin(Body), with slate legs . But I have chickens that are white skinned with white/pink, & Slate legs, yellow skinned birds with yellow legs, yellow skinned birds with green, & dark legs, black skinned birds with black legs.

That's quite a variety!

I thought the gene Id (inhibitor of dermal melanin) affected shank color, and I assumed (but didn't check) that the rest of the skin simply looked the same.

All the leg-color charts show it being involved in shank color: Id is the dominant for light skin, found in birds with white or yellow legs; id+ is the recessive for dark skin, found in birds with slate or willow legs, and also needed for Silkies and Cemanis to express their fibromelanosis.

So if that gene is controlling the shanks, your rooster would be id+/id+, your hen would be id+/_, and their son would be id+/id+

That would make him NOT a skin-color sexlink.

I'm getting my information from pages like this one:
http://kippenjungle.nl/sellers/page3.html
It lists several alleles for id, and specifically mentions that only one allows the dark color to be seen in day-old chicks (vs. older chicks.)

So no matter what skin color you are finding on the rest of the chicken, I think for sexing purposes you have to look at the shanks, and that cockerel is NOT a sexlink. Unless the sources I'm reading are just plain wrong (which is admittedly possible, although I don't think it's likely.)

Well, like I said, I can do a hatch next year to confirm if this is sex linked, or not.
The chick's shanks were pink at hatch, turned slate a week ago. For some reason I forgot to get a picture after it hatched.

Not saying you're wrong, just sharing some results from experimental crossings.

@nicalandia

Thank you again for sharing your brain power to answer so many questions and with clarity!

My query is can I get blue crossed to lavender (of any single specific breed) to breed true producing only blue and lavender offspring and if so would you please describe the generational breeding steps required to achieve this.

I understand that most breeders never suggest doing this. Are you able to tell me what sort of fall out you might predict as to why they're against it?

Blue + Lavender produces a very light colored bird, the issue is that Blue(Bl/bl+) does not breed true and Splash and Lavender would produce a nearly white bird.

Question.
Does the slate legs on the Red JungleFowl hybrid/Silkie cross make it Not a Skin Color Sex Link? Could a Fibro Sexlink have slate legs?

I sexed it as male at hatch due the skin color being white/pink(Legs) at hatch.

I have a female of the same crossing that has black skin, & shanks from a year, or two ago. Sexed the same way.

I hatched the gold laced Isabel splits and gold laced chocolate, what would those 2 colors produce? I'm just trying to see what my options are for selling them or breeding them

So, would the Isabel dilute the gold laced chocolate? And if so, what would the resulting color be?

I learned the hard way about this crossing not being successful

First question:
Both pictures are the same bird. From a [failed] sexlinking pair. The baby turned into a Boy. Is that why he hatched light and turned dark? Or do correctly paired dark skinned sexlinks all hatch light and turn dark?

Edited to add, the other sexlinks all turned out correct, but they weren't naked necked so I didn't happen to see what color their skin was until their combs started to come in
