Looks like it to me, Jay. Remember, though, that the sexing is not 100%. My Lexie had a huge, splotchy headspot, lighter legs than the others and lighter color overall, so she was completely opposite to every BR pullet I've ever had since.
Here are chicks from my own stock, to show what they're talking about. Even though the spot may be tiny, there should still be one 99% of the time. Yes, boys are lighter. :

This pic shows boy at bottom of pic and girl by the screen door:
Wait about four weeks on the RIR's then look at the legs-cockerels have thicker legs and the comb and wattles start to get larger than the girls. I have a good comparison pic of two that I hatched, brother and sister at four weeks, if you'd like to see it, but I don't want to horn in on...
That would be highly unusual. ALL BR chicks should have a white headspot. Did you hatch these or buy them? Sexlink pullets would have no headspot, but BR girls should have at least a small one.
