Sex linked white egg layer?

ah.. I see.. then still no. production Black hens are made by using a barred hen over a black roo.. making the hens black and the roos barred.. unless you use a barred hen

Ideals Production Blacks are basically a barred leghorn and they breed true, roosters and hens are Barred so they should work.

Chris

I wonder why they called them production blacks...

Beats me.

Welps calls them Production Black (California Grays)

I don't know what they call them that either but they are all barred both hens and roosters. I was just talking to a member here a few days ago about hers and she has a pic of a really pretty Pro. Black/ Cali. Grey hen.

But Caprice Acres, with Production black hens, you could use your choice of Red Leghorns, Brown Leghorns, Buff Legnorns, Blue Andalusians, Mottled Anconas, Minorcas, and pretty much and other white egg layer rooster other than the Pro Blacks since they are barred and White Leghorns since they are dominant white, but any others you want to use will make white sexlinked egg layers. A Buff leghorn on the hens would make pretty sexlinks, they will have a lot of buff on the chest and the extra buff on the pullets makes them even more distinquishable as chicks

Most any color Male over a Barred Hen will produce Black Sex-link offspring.
The only time you need a Gold Male is when you are producing Red Sex-link offspring then you would breed Gold Male over a Silver Hen.

So then a BCM cock over BR hens would work? I've played with this idea to produce BSLs that lay a darker egg. I have an extra BCM male from a batch of chicks I hatched this past spring, and the pullets are now laying eggs so dark they are almost purple! I'd love to justify (to the DH) keeping an extra roo "just in case," and if he were producing BSLs, which the DH adores, that would do it!!

Yes that will work also

True California Grays carry the sex linked dilution gene, which makes the roosters almost white and hens barred. but I don't know if they are produce anymore.

Most pure barred breeds are autosexable to a pretty high degree, but I have also heard its more distinct in Cali Greys.

that's because they are not "Barred" per say.. they carry B^sd which is called sex link dilute.


Females that are hemizygous for B^Sd (having one B^Sd gene) have light blue and barred plumage as do the heterozygous males, however, homozygous males show a dosage effect and are essentially white. These homozygous males resemble dominant whites but differ in that they are epistatic to pheomelanin while dominant white is not


Edit...to add some thoughts


let me quote a dear friend of mine.

Flowery Leghorns could have the B^Sd Sex linked Dilution gene also. but its not confirmed

Oh cool, I wonder if there are any like that still around. I don't think Ideals have that variation, I think they are barred kinda like most barred breeds, that may be why they are called Production blacks because they were crossed with something.

The color in the ones you posted may be similar to the dimorphism in Pilgrim Geese. That's interesting.

Here is the pic if found of stephanie1992's hen from Ideal.

This is an old thread, but I just came across it. Norwegian Jaerhons are wonderful layers of large white eggs. They are autosexing and it is easy to tell the males from the females at hatch. They are small so they don't comsume a lot of food and though they are active and free range well they also tolerate confinement. I really enjoy mine and wish more people knew about them.
