Cream Legbar cross genetics and (auto)sexing

[Chris09]

If you cross a Legbar with a Barred Plymouth Rock the chicks should be sex-able by the head spot at birth just like a Plymouth Barred Rock.
As for the color as adults, they should be somewhat the Legbar color but with better cleaner barring. More a Crele color.

Thanks Chris,

That's what I was guessing (about the head spots), but I wasn't sure how the other traits would come into play and if they might make things more confusing.

If you cross a legbar hen with a non-barred rooster like brown leghorn hen, you will get sexlinks where the cockerels are barred and pullets are not. Otherwise there really isn't a reliable sexlink cross using the rooster that I can think of.

what about a legbar with a welsummer or crele penedesenca? all three are autosex types

I have a few of these that I want to breed back to a crele penedesenca roo

you cannot sex when crossing a autosexing with a non sexing breed

Barred Rocks are a Sexing breed...

Well, I just took the plunge at the San Diego area meetup and bought a pair of Cream Legbar chicks.

I am trying to plan ahead and think about what other hens it might make sense to put in the same pen (since I have only one Cream Legbar female), particularly if I hope to be able to sex the (mixed) offspring by coloration at hatch.

Does anybody have either theoretical or practical knowledge on this matter? I am guessing that if one bred the Cream Legbar roo with black barred hens (e.g., Barred Rocks), it might be possible to sex with some (perhaps imperfect) degree of certainty, if one knew what to look for.

I say this since Barred Rocks can usually (I've heard 90% of the time) be sexed at hatch by coloration. And a Cream Legbar x Barred Rock chick would get the barred gene from both parents. But perhaps some of the other genes would do unpredictable things to the coloration.

Any thoughts or experiences to share?

if I were you and I want more cream legbars, I would use light brown leghorn females or brown leghorn females(about 5 of them will give you lots of white eggs to hatch) raise them up, use your best looking rooster over you cream legbar hen(separate pen just for them) and in a different pen use your best looking hens with your boy, that way you will have 2 separate lines and after a few generations you could use the best of both pens and mate them, this will give you fresh blood, but keeping the other 2 lines separate,

I crossed my Cream Legbar Roo with my EE hen who is white and a grey Cochin and these are the two chicks that I got. I can clearly see chipmunk strips on the light chick and a head spot on the dark chick. So my question is: Am I right to think the chipmunk is a hen and the one with the spot is a roo? Or does it not matter because the momma hens weren't barred?
Thanks,

Thanks,

the Black chick may verywell be a hen also.... Why? because 100% of the hens and males will get the sex linked barred genes....

the white hen may very welll be Extended black or Birchen with a single dose of dominant white... making the black chick a E/e+ B/b+ and i+/i+(black barred male) or E/e+ B/- i+/i+ which is a female

Quote: I was re reading my post and I think it was a little confusing. Then hen in the pic is not the mother, just a broody I used. Both chicks have the same dad, Cream Legbar. The light chick came from an EE (pure white) and the black chick came from a Cochin(grey/silver). So the light chick (w/ light Chipmunk stripes) is a hen? And the black chick (w/ a head spot) might be a hen or a roo?
Thanks for you patience, I'm new to all this stuff.

well from those pics(need better one and a close up to the head) the light chick looks like a wildtype e+ hen with dominant white I/i+
