Six different breeds 2 weeks old - pullets and/or roos?

Aren't Black Rocks just one name black sex links can go by?

Sometimes yes, but they do not breed true.

So either the seller has a pen set up to produce black sexlinks (one color of rooster, a different color of hen), in which case that chick would have to be male because of the barring.

Or else the seller has "Black Rocks" (black sexlinks) that they are using to produce chicks, which would make mixed chicks that cannot be sexed by color. In that case, a chick with white barring could be male or female.

I know they don't breed true. I read your previous post as saying it couldn't be a "Black Rock" if it's black with white barring (though looking back at the photo it has the head spot but the wings don't really look properly barred) but now it seems like you're saying there are two ways someone could end up with a black chick with white barring that was sold as a "Black Rock", so I think I've probably misread you somewhere and got confused

What I really meant was, Why are they calling it a "Black Rock" if it has white barring?

Most private sellers do not have the correct pens set up to produce any kind of sexlink chick. And some people think (wrongly) that if they breed a male and a female of some kind of sexlink, they will get more of that kind of sexlink.

So I am suspecting there is something not right about the way that seller is labeling the breeds.

So I speculated on a few things that could be going on. I think I may have confused myself by now :lol
