Would a red sexlink mix still be auto sexing?

[TheBeardie]

The lady I got the eggs from has a few red sexlinks along with Olive Eggers, EEs, Marans, Ameraucanas, Leghorns, Sussex, Red Sexlink, Salmon Faverolles and naked necks.The chick's hatched a few days ago and I'm trying to figure out some of the breeds they could be. I know a red sexlink is not a true breed and they are auto sexing. Would a red sexlink mix still be auto sexing?

No.

No, any generation but the first will not be sexlinked. Even breeding a Red Sexlink rooster to Red Sexlink hens will not produce chicks that can be sexed.

I figured, I guessed that the auto sexing breeds are usually finicky like that.

I believe you are confusing autosexing with sex linkage. Autosexing breeds such as Cream Legbar can be sexed at hatch as the females have different down than the males; female chicks get more of the chipmunk pattern than males, whilst males get more barring. A Cream Legbar hen could be used with a non-barred male to produce black sex links as she is barred, but only capable of passing that barring on to her sons, not her daughters.

Red sex links, however, are created by using a gold based cockerel over a silver based hen. They are not autosexing, they are a sex-link. A silver hen can only pass that silver onto her sons, not her daughters. Therefore from a RSL crossing, all the cockerels have one copy of silver (from mum) and one copy of gold (from dad), whilst all the pullets are gold as they only have one 'slot' for either ground-colour, which they always get from their father. With that in mind, once the cross has been performed once, it wouldn't work again; all the females are gold and therefore will pass gold onto their sons, whilst all the males are both silver and gold and will pass either onto their offspring, therefore there will be gold males, 'dual' males, and gold and silver females; the gold males and females will look identical as chicks, as will the silver females and 'dual' males.

The only way to create a sex-link from a sex-link is to use a RSL cockerel over barred hens, however in this situation that won't be of use to you.

Just watch for comb growth and redness and you should be able to tell them apart within a few weeks.

Thank you for all the information. I don't really know much about any of the breeds that can be sexed at hatch. I was just curious about them.
