Is the breed correct

I got my chickens end of March from TSC. 4 are RIR, the other 8 were bought as 4 sapphire gems & 4 blue Plymouth rocks. I’ve heard/learned that sapphire gems & blue Plymouth rocks are essentially the same. My question is, Midnight, the black chicken, is she either of those breeds? She doesn’t look ANYTHING like the other 7 sapphire gems/blue Plymouth rocks. All of them are colored like Paisley, The rooster in the pic. Does anyone knows if she’s the same & if not, what breed she is? Thanks!

Off topic, but do you still have your rooster? He's beautiful!
