Brown Leghorn Pullet, or not?

[Little Chix 2023]

These 2 Brown Leghorns are 6-8 weeks and are to be pullets.

The smaller one was mostly feathered we hen we got her.
The larger on was still fluffy with minimal feathers.

I’m starting to doubt the breed of the larger one.
It has doubled in size of the feathered one.
The smaller feathered one is also very skittish. Totally different temperament.
Then I had someone question if the larger one was a turkey

Thoughts?! I also included a pic the day we brought them home, in a box

The one with the pink legs looks like a speckled Sussex to me. They both currently look like pullets, but are young yet.
