Silver Laced is not barring. Lacing is the result of multiple pattern genes. Barring is a modifying gene. For color sexlinking, it's the hens that must have the sexlinked genes.
If you got white chicks, the rooster is dominant white. Not the best choice for sexlinking, since the white will mask any barring present. Any chicks with barring will be male, but the white ones will be wait and see.
