If you use a Cream Legbar hen you can use her like you would a barred hen to make a sex-link cross. So...I think it depends what you use as a rooster. You can't use dominant white, for example. I have two Cream Legbar hens in with my Black-Copper Marans rooster and I get sex-link Olive Eggers. The chicks are solid black with the cockerels getting a tiny white blur of a spot on their heads. Once they feather out the hens look like a Black-Copper Marans with maybe less copper or less feathering on the feet. The roosters will be barred like a barred Plymouth Rock.
