Cream legbar/welsummer auto-sex?

[Bush84]

Hello all. I decided to try my hand at an olive egger. So I am hatching out cream legbar roo vs welsummer hen. My question is, will I be able to autosex the chick as I would a cream legbar? I know welsummers are also able to be sexed at hatch but wasn't sure if a mix would change things.

Have to have a Welsummer male over Legbar females to have autosexing. Males pass on the barring to both sexes, females pass the barring on to their sons only.

I'm not sure I follow you as to the why. I though they were both autosexing chickens, but to me it seems to me my cream legbars chicks have had more definite feathering than my welsummers. If what you say is true I'm hosed as my welsummer Roos died this winter.

Barred roosters pass on their barring to both sexes of chicks. Barred hens only pass on their barring to their male offspring. Welsummers are only autosexing in certain bloodlines that have been bred for it. And it will be lost in the first crossing.

So what you are saying s that because I bred roo legbar to hen welsummer my hens will only have one autosex gene and therefore it won't be expressed? Does that then mean that the males will carry both genes and will therefore be expressed? If so then I will essentially still be able to tell the males vs females at hatch. I'm not looking to breed this gene into these olive eggers, simply to tell the difference right now.

All the chicks will be barred and won't be able to tell males from females.

A hen can only carry one gene for barring. A rooster can carry one or two genes for barring.
The legbars are autosexing because the cockerels carry two genes which makes them look diiferent then the pullets with only one gene.
With your cross the cockerels only get one gene since the welsummer hens dont have a barring gene to give them the second gene. Your chicks will look alike since both sexes have one barring gene.
If you would of been able to use a welsummer rooster over legbar hens then the pullets wouldnt get any barring but the cockerels would get one copy from the legbar hen. That cross is a sex link since cockerels would have barring but pullets wouldnt

Cool beans. I guess I'll have to do it the old fashioned way and wait. Thanks all.

My chicks from a Welsummer rooster with Cream Legbar hen were sexed just like the parent breeds are. It was very obvious who was whom!

Welsummer male over Legbar females will produce sexlinked chicks. But not Legbar male over Welsummer female.
