Do all Barred Rock chicks have a white star on their heads?

Updated pics. These guys are now 5 weeks old. As a reminder, these were supposed to be barred rocks but it looks like at least two are female black sex link. It looks like the other four are either male black sex link or maybe male/female barred rock.

Male? Barred Rock or Black Sex Link?

Much lighter than the rest...male barred rock or just a lighter variation BSL?

Female Black Sex Link...

Female Barred Rock or Male Sex Link that just hasn't started maturing yet?

Thanks Gray Farms. This seems right.

Here are some better pics. I am beginning to wonder if I have two different breeds. The solid black are smaller, and have black combs and legs/feet. The ones with the dots on their heads are bigger, and have yellow combs and legs/feet.

1st one (seems to me), to be a female black sexlink, whereas the next one is a barred rock, unsure of gender.
