Mystery Chicks

Need help identifying mystery chicks. I got four chicks and I’m unsure of what breed they are or if they’re a hybrid. The first photos are of the chick that represents the other two that I have. Then there are photos of the chick that doesn’t quite fit in. it looks similar but has more white and less patterning on the feathers. I got them at tractor supply. I was told what they think they are but I’m curious to hear what everyone thinks without that influencing any research.

These chicks have:

-Creamy almost white down

-Yellow legs and beaks

-Feathered outer legs and middle toes

-Gray head spots varying in size from a pea to a nickel

-Possible pea combs or maybe straight combs (hard to tell this early)

-They can’t be more than two weeks old id guess

-They have four toes

-Gray patterning on wings and tail feathers

Let me know what you all think!
