Sex- linked Information

[chicken pickin]

Hello!
Just found out today that I have a Black Copper Marans rooster ( was told it would be a hen, it is crowing now, there is no doubt we have a sir!), I also have a Crested Cream leg bar. If I mate my Marans rooster with my leg bar hen, will i get sexlinked chicks?? I know that CCL are auto sexing, but wondering if I can get some olive eggers that I can sex at hatch.... (totally new to this, but looking towards future!)
Thanks!!

Yes that cross will create sexlink olive eggers. The legbar hen does not pass her auto sex trait as she would if she was crossed to a legbar cock. But because she is barred she will pass on her barring gene to all of her sons. They would be considered black sexlinks.

I don't think you will get sex linked olive eggers. You will get some olive eggers though. For the sexlink information go to the first page of this thread and read it. It will answer your questions.

Yes barred hen and non barred rooster will make sex links . Males will have the white head spot at hatch .

With the added stipulation that one of the parents must be homozygous for extended black (refer to the orig post to confirm this). CCL's are not EB, but BCM's are, so I believe you will get black sex-links from that cross. The key is the color of the chick down, BCM's produce black chicks. I don't think a Welsummer roo over CCL would produce black sex linked chicks, though the roos are very similar in color, because WS chicks are wild-type, not EB.

Black is not the only color used to make sex links . It mostly depends on chick down color when using sex linked barring . Very light chicks make it hard to see the white head spot when barring is used . Buff , wheaten and white are not suitable for use with sex linked barring .Wild type works fine . Go back to page 1 of this thread for a more complete list .

Agreed, but there was a reference in one of the responses to "black sex links" (that does need EB), and generally when people are looking to make sex links with barred hens, they are expecting EB chicks with male head spots. Wild-type can work, in fact that is the basis for the CCL's (and other *bars) auto-sexing, but I would not count on a non-EB male creating sex-linked chicks from a CCL hen. It might work, but I got the impression they were looking for a "sure bet", in which case EB is highly recommended, and BCM's provide that.

I had some "blue sex links" last spring (splash roo over BR hens) and I was fairly sure I knew the sex, but the lighter down made it harder to be sure, and we all want to be sure, that's sort of the whole point. I want my color-based sexing to be 100% and very obvious.

Could you elaborate on the blue egg shell gene being carried by the male. So for example if crossed a Blue Copper Marans to RIR hen what color will the eggs be? Dark green? Olive egger?

 

[dheltzel]

Neither BCM's, nor RIR lay blue eggs, so the progeny would lay brown eggs, perhaps some intermediate shade between the 2 parents, but there are several genes involved in getting the brown egg color, so it's hard to say.

 

[Ridgerunner]

The blue in Blue Copper Marans refers to feather color, not egg shell color. Two totally different things.

The eggs would be brown but the exact shade is hard to determine like Dheltzel said.

Oops I forgot to add the blue CM was out crossed with an Ameracauna so was het for the blue egg colour. Sorry my bad
