Bantam breed?

[jen61871]

I got Chicks-bantam from tractor supply for a dollar each because they are "old" at 3-4 weeks.
They could not tell me the breeds though. Can somebody tell me the breed of these two Chicks?
Thanks so much!

I can't help with the breeds but they look more like 2 weeks old.
Super cute!
