Another thing I've noticed about sexing the cream Legbars, is that they didn't go through any phase where the autosexing chick down color was lost, before the male barred color came in. I was worried because one of my pullets was the exact same light shade as my cockerel. And I thought that I might get them mixed up for a while when they lost their chipmunk stripe down and head spots and eyeliner, before the cockerel developed male traits. But that didn't happen. He started getting his barring before he lost his white head spot. And the pullets pretty much kept their eyeliner until I could see their non-striped female feathers.
So if it helps, they retain different characteristics throughout their development, so far as I have seen.
