She is an EE, but I wanted to be certain she is not a he because she has very long tail feathers, tho you cant tell how long in the pic, and a very dominant demeanor.
I still think pullet, I have 2 whites and ones a cockerel and his tail feathers are extremely long. Maybe a closer pic would help. She has not tuffs or muffs or whatever peeps are calling them, so if it was a boy it would have some very little wattle development.
