Hapless Runner- have your read the sex-linked thread? https://www.backyardchickens.com/t/261208/sex-linked-information Post 1 is long but VERY informative. I will apply my (limited) knowledge to your situation:
Sexlinks are made two ways.
1. Non-barred rooster over barred hens. This creates boys with a head spot and girls without (most black sexlinks/black stars are produced this way). You cannot create sexlinks with your setup because you are using a barred rooster (Cream Legbar). You will not be able to sex any mixed chicks using headspot. The headspot chick appearing male is purely coincidental in your case.
2. Gold (red)-based cockerel X silver-based hen. This creates gold/red female chicks and silver/white male chicks (most red sexlinks/red stars are produced this way). It is POSSIBLE you could come across that with your EE hen as there is no way to know if she is silver based or gold based without test mating. You could grow them out and see if it works.
As you can see from the sex-linked thread it is much more complicated than this, as some breeds work better than others even if they have the correct barring or gold/silver genes, but that is the simplified version of how it works.
Sorry for my limited knowledge of Cream Legbars But would they be considered to carry the gold gene? I have noticed that when I cross my legbar rooster over my silver laced cochins and silver laced wyandottes only 2 colors chicks are produced. Ive only done 2 hatches so far but even before reading this It seems my reddish brown chipmunk chicks are pullets while the silver and black chipmunk chicks look like roosters. Could I have possibly made sexlinks with this combo?
