Question about black sex link

[Bert96746]

Hello. So I just hatched out 6 chicks. The dad is a buff orpington and I'm pretty sure some of the moms are barred rock which I've read will create sex linked chicks. I've attached pictures so hopefully I can get some input. Thanks in advance ☺

It kinda looks like one, but I haven't had those kind of chicks for almost 9 years
