EE or Ameracauna? 7 week old chick

[ARose4Heaven]

Since it came from McMurray, I am thinking EE. Hoping Female. Of the 100+ birds I have in this bunch, there are others that I am calling Partridge Rocks with this coloring, but only this one has this fluffy head and upright tail.

3 pics...all the same bird. 7 weeks old tomorrow.

And a Pic of a few of the crew it came with....

If it's from a hatchery, you don't have to ask - it's an EE.

And yes, she's a pretty little pullet
