Sex- linked Information

Hi Tim,
What colors do you get in plumage and eggs if you cross production white leghorns with SOP Light Sussex?
No, I am not planning to do this. Just curious?
Thanks,

white adult plumage and cream colored eggs. White will show some specs, blotches or partial feather black. The amount of black varies. White shank color if leghorn is male; sussex male produces white shanks in males and slate to gray on female depends on E locus of leghorn

similar to this

Hello to all,
I have Bielefelder X Delaware cross chicks in the brooder and more in the incubator. Of the five in the brooder four are reddish and one is white. I believe they are sex liked like the first pictures in this thread. (gold X silver) I am trying to verify this as I would like to be able to sell them as such. Greatly appreciate any help. Thanks

Would this work with a Splash Ameraucana roo over a Barred Rock hen? The sons would be blue barred and the daughters would be solid blue... and another plus; they would be easter eggers and decent dual purpose birds. Anyone tried this mix before? If so, pics please! And you could cross the daughers back to a BBS Ameraucana roo to improve easter egger/ameraucana qualities like muffs, slate legs, blue eggs. Those offspring wouldn't be sexlinked though.... would the original blue daughters be silver so you could do a red sex link breeding with those? Perhaps with a buff/wheaten/blue wheaten ameraucana roo?

You never know for sure what the Splash roo is based on, but it’s probably Extended Black. In any case it should work to make a black sex link chick. And yes, you should be able to see the spot. I know this is a long thread but blue for black sex links been discussed on here before, probably not a whole lot of pages back.

The Barred Rock hen should be pure for Extended Black. The Splash roo probably is too. That means the pullet should be pure for extended black. It doesn’t matter what red rooster you cross her with or whether she is Silver or Gold. Her offspring should have pretty solid black down. You won’t be able to see any yellow or red down.

Yes, if you cross those blue daughters to a true Ameraucana rooster, you will enhance the Ameraucana qualities. But the black rock hen will contribute some genes too so you’ll need to do some culling. The blue daughter is a cross and you are never sure which of her crossed genes she will pass down.

I'm SURE this question has been asked before, but I can't find the right answer, and it's not in the chart - so I'm not hopeful the answer will be yes.

Could I use Barred Rock hens with an Easter Egger rooster to produce black sex links? Are the EE genes too much of a wild card?


Hens


with this male.

I do have an all white Easter Egger male..

Your cross will be a black sex-linked cross.

Out of the first post

The second important rule is that one should not use white birds in sex linked crosses. White birds that have the correct genotype can be used to make a sex linked cross but a breeder never knows if the white bird has the correct genotype. The authors advise concerning white birds and sex linked crossing is do not use white birds in sex linked crosses. White leghorns can not be used in any kind of color sex linked cross.

5). Almost any variety (color) of male ( not including white or barred ) can be used in a black sex linked cross. White birds sometimes carry dominant white and or barring which would not work in a black sex linked cross. White males that do not carry dominant white or barring will work as the male in a black sex linked cross. White males like the white wyandotte or the white plymouth rock will work if they do not carry dominant white or barring.

Tim beat me to it. I was going to say look in post 870 in this thread. The barred rock is pure for extended black.

That's what I figured with the white. He is definitely questionable.

Thank you for clearing that up! I'd really like to have some sex linked Easter Eggers. I do realize not all will lay green eggs, but some will - and I will be able to sex them at a day old Big bonus.

i know a RI red rooster X silver laced wyandotte hen will produce sex linked chicks. but will the pcomb of the wyandotte be dominant? is there a percentage that will be SC and PC?

and another question:

will a black copper maran over silver laced wyandotte hens create a sex linked offspring.
