Looks like my 5 week old EE pullet. Mine's head is turning red like the chest on your's. That stripe on your EE's head will most likely turn red/orange and spread out .
This was my EE pullet, Harley, weeks ago. You can barely see it, but she has a stripe on her head too, we called it her mohawk.
Here she is today at over 5 weeks old. Her mohawk turned more orange and spread out! Her beard is also coming in, or what we call it, her 5 o'clock shadow.
