What type of chicken?

[Cgraichen]

I originally got 3 chicks from tractor supply and was told they are light brahmas. After looking up light brahmas a day later, I realized they are absolutely not. Not quite sure what they are. I’ve included a 1 week and 7 week photo.

Looks like a speckled sussex. send another picture after she molts or when her head feathers are in.
