The Tractor Supply in our area is crap too. I was told the two bantams I got were silkies. Sadly I was still too much of a novice to realize they weren't. Called the manager and she's like oh, well they came in a box marked assorted bantams. They were Mille fleur d'uccle bantams. But that's all good, one turned out to be a beautiful roo!
Just go to all the different feed stores near you until you find a good one. I have the options of four different places. One they sell boring breeds, two they mislabel breeds, but the last is amazing. They get a huge variety including game birds, they actually know about the chicks (!) and they're very accommodating. They sell thousands of chicks every year, which is amazing since they're in a semi rural area. You just need to find a reliable store.
I have no idea what breed yours are, but I have Black Australorps and those aren't.
