Olive Egger breeding

[lolli1103]

Hi, I am trying to learn chicken genetics. I have a question if anyone could help me that would be great. I have a crested cream legbar Roo crossed to a Partridge EE hen. The result is my Legbar EE cross Roo. Whom I am planning to breed back to an brown partridge EE hen. Who is a cross between an Australorpe hen and a EE roo on her maternal side and a Leghorn roo and EE hen on the fraternal side. Can I hope expect any chance of his chicks carrying the legbar auto sexing trait

No chance.
The legbars auto sexing is very specific to their genes and the offspring must get barring and wild type plumage from both parents.
Once you've elimated either gene or added others the auto sexing is lost.
