I have 7 chicks I got from TSC and I was told 3 of them are Blue Laced Barnevelders but after looking at chick pictures online I’m starting to question if they are actually the breed I was told? They’re about 11 days old. All help much appreciated

That is false my feed store sold silver laced barndvelender their not common ether.Looks like Barred Plymouth Rock, feed store's wouldn't have blue laced Barnevelders. At least not until the breed is more common.
You cant be so sure she has to wait 6-8 weeks.I wonder if you got male Blue Sexlinks....They're known by a few different names, but Sapphire Gem is a common one
Looks like Barred Plymouth Rock,
Feedstores are carrying Blue Sexlinks more and more lately. In those crosses, males are blue barred and females are just blue, all these appear to be blue barred... I am not aware of any mix commonly stocked that has blue barred females. Time will tell though, this is just what I suspectYou cant be so sure she has to wait 6-8 weeks.

You may be right. To me they look more blue, but yeah, if they're black I agree that Barred Rock would be likely!I thought I was seeing black chicks, not blue ones--probably my computer is showing the photos differently than yours is. If they are blue, I agree they would be Blue Sexlink males, for the same reasons you gave: that's the most common kind of blue + barred chicken, and only the males would have the barring.
Real ones? I wish my feed store didThat is false my feed store sold silver laced barndvelender their not common ether.
