EE chick not acting like a lady - can behavior indicate if it is a roo

[rusteerooster]

We purchased our first chicks two weeks ago. They are all seperate breeds, EE, Barred rock, welsummer, buff orpington(that’s what I get for taking kids to pick out chicks). Our EE chick was supposedly vent checked and confirmed as a pullet. However, heshe is not acting very lady like. Heshe is a spaz compared to the other chicks and extremely aggressive towards the bared rock. Heshe will run full speed at the barred rock, lunging feet first into the back of the rock. Heshe is also a bit of a bully toward the welsummer and buff(they’re so gently it makes me angry to see him rough them up). Also, Heshe will pace actively from one side of the cage to the other several times then launch an attack, most of the time the other chicks will meakly move to a corner of the cage when this behavior starts. Occasionally the barred rock will stage a counter attack. Heshe is almost a solid white at this point, with what looks like light green around the eyes, there might be some light brown on top of the head, otherwise the bird is all white at 2 weeks. If I tap on the side of the cage or otherwise scare the chicks, heshe will stand tall and stare intently at where the noise came from, the other chick freeze or head to a neutral corner. Based on behavior, is it possible to tell if the bird is a roo or not? Are EE chicks naturally more aggressive, it is almost opposite behavior compared to the other girls. I can post a picture if that helps

Thank you,

My two EE are pretty aggressive. The blue is the head chicken. She bosses everyone. She is a little mean about it. Also if my lab puts her nose to the wire of the run, she gets a good pecking. When we got the 3 new chickens, she ignored the barred rocks (probably because they ran from her), but she was obsessed with the new EE. She chases her and the new EE is a little mean to the other birds. They are both great to us and have never brought blood, it is more of a warning.

Of my baby chicks, the EE is the most outgoing also the most friendly to us.

I have two EEs. one is completely scarred of everything and avoids all contact while the other attacks everything and is Very outgoing.

It's funny how much personality they have.
