Sex- linked Information

[Ridgerunner]

I don't know the genetic make-up of the California Gray hen. From a quick look online, it looks like the breed was developed from a specific cross, but that was many decades ago. Most breeds were developed from crosses, but they are now specific breeds. Although the Califirnia Grey is not an officially recognized breed, it is a breed nevertheless and all members, male and female, are barred.

If the rooster you use is not barred and the hen is barred, all the female offspring will not be barred and all their male offspring will be barred. In that respect, yes they will be "Black Sex Links" and the males will have that spot on their heads. Where my lack of knowledge comes in is that I don't know what the offspring will look like other than that spot. Due to the color of the chicks, you might not be able to see the white spot.

Delaware are barred. When I crossed Delaware hens with a Speckled Sussex rooster, I got red sex links. The males also had the barring and the females did not, but due to the color of the male chicks, I could not see the spot.

I think they'll be pretty.

I haven't done that cross so I cannot be sure. And as I said, I don't know the genetics of the California Grey. It is possible she could have Silver. I just don't know. If the hen has Silver, you should be able to put the chicks side by side and get a pretty good idea of sex. The males should be yellow where that chick is reddish. If the hen has Silver, that would be a female. If the hen does not have Silver, that chick could be either sex from that aspect.

But since she is barred and the roo is not, those chicks look like a white spot should show up on the top of the head of the males and the females should not have a spot up there. From that coloring, I think you would be able to see it. Again, it would be god to compare a few chicks side by side since the differences can be a lot clearer. I can't see the top of that one's head too well, but it looks female to me.

If you look at the barred rock chicks on this link, you can get an idea what the white spot should look like. Both male and female barred rocks will have it.

Yes and no This cross will not work for red sex link. Will work for black sex linked.

PS. I thought they were wanting red sex linked. I changed my answer.

Why not Tim, the Hen was Barred, IF this chick is a boy it should have a dot in his head, if not, then is a girl.. am I right?

 

[scoopy82]

Another quick question - would a silver spangled Hamburg be considered a barred breed?

No on the barred. They would act as silver for a red sexlink cross though.

do they look barred?

sex link barring is a very powerful gene, if you don't see it, then is not pressent, Unless the bird completely white and hides barring under it..

Does anyone know if a French Black Copper Maran roo over Delaware or Light Brahma hens will produce a sex-linked cross?

 

[BlazeJester]

I would guess that BCM would be brown Columbian, or group 2A (roo) in the OP. Delaware is in group 1 and Light Bramha is in group 2A (hens) so yes, those should produce red sex links IF the BCM is indeed a brown Columbian.

Read the OP carefully, it talks about how difficult it can be to distinguish between gold and silver in the 2A/1 cross (I believe that's the combo).
