Sex- linked Information

[Ebove06]

If you cross a buff Orpington with a cuckoo marans, will you get a black sex link? If so, how will you be able to tell the difference between the boys and the girls?

You should be able to figure it out by reading the first post on this thread. There is a lot of information good there.

Only if the cuckoo Marans is a hen. If your rooster is cuckoo Marans, none of the chicks will be sexlinked. They should look like any other black sexlink at hatching.

I've been working my way thru this thread but wanted to pose a question to the experts.

Would a Red Orpington over a Crested Cream Legbar produce a Red sex-link? Is the "red" in the Orpington the right kind of gold? And is the Cream Legbar silver enough to work? I think the chicks would have "wild type" down as in example #2 on page 1. Am I thinking correctly?

I think since cream legbars originated from crossing Brown Leghorns and Barred Rocks, they might not have the right genes to produce a red sexlink. I may be wrong, but I don't think they have a dominant silver factor since cream is a gold/red gene. Again, I might be wrong about this, but if you really want clear red sexlinks, you should probably use a hen with out any traces of red/gold.

Cream is not sex linked . Silver is sex linked . So wrong combo for red sex link . However you have sex linked barring in cream Legbar . So you would be able to tell the males by the white head spot . The hens must be barred and the rooster not barred . Which is what you have in that cross .

if the orpingtons are wheaten based, that may cause problems with seeing the head spot on the wheaten chick down(not enough contrast)... in general, wheaten is dominant over e+ but it can be a little confusing and variable and as result, sexing may be variable.

Thank you. I was thinking the cream was silver based - still trying to figure out genetics in general.

I was thinking that a black sex link wouldn't work because the Red Orps hatch with pale down; but the Cream Legbars have the wild-type stripes so I guess if they all hatch with stripes then the spot would be visible.

Ok now for the real newbie question - how do I tell if he is "wheaten based"?

Yeah it seems legbars are still being figured out- why are some so light, others not and so on. I avoided that part on purpose.

Buffs are wheaten so I figured but was not sure if the reds were too but as it happens, you answered in the affirmative with the description of pale down- that's how wheaten chicks look.

Your issue probably would be trying to see a smaller head spot due to single dose of barring on the paler downed chicks. Not all chicks would show sufficient contrast to show off the diluted head spot...

Thank you so very much! I might just have to give it a try and see how they hatch out.
