Is this pullet any breed or a mix?

[Amelise]

My grandparents got 3 cheap 8 week pullets from a local breeder, and I’m trying to I.D what breed one of them is.
I’m guessing it’s an unofficial breed/not bred to standard, or a barnyard mix? This breeder said what breed it was but they didn’t quite hear what she said. The breeder also said it’s supposed to be a good layer. The other two are low quality wyandottes. These are the only photos I have to work with.
Any ideas of what she could be are appreciated!

Comparing it to some pictures, it actually kind of looks like one of those sex-linked production mixes
