Mean 4 week old chick

[SGH]

Hi all, I have 20 chicks in a brooder that are 4 weeks old. About a week ago, one of the Easter Eggers has become a bully and is mean. She/he grabs the feathers on the back of the other chicks necks and won’t let go for a couple seconds while the other chicks screams and tries to get away.
Is this normal? Is this a cockerel behavior, or do pullets also behave this way? The EE I ordered were sexed, and it should be a female, but we all know how that goes ha ha.
Is it normal to have a bully as young as 3-4 weeks?

That is normally boy behavior. Little bit early to tell but do you have a picture?

I see now a bigger redder comb than the other EE. So far I’m thinking my 4 sexed female EE one is a rooster.

That well defined comb and faint beginnings of coloring coming in at the wing bows do point to cockerel

The coloring and the way it's standing on the food jar make it look like a hawk! You sure it's a chicken?

Cockerel for sure and the behaviour is normal for a little boy.

I know, right! And I swear, he ran wild, knocked off the funnel, jumped right on top and struck a pose the second I went in there to take pics!

Ever see the episode of Mad About You where the sister adopted what she thought was a house cat but it ended up being a puma? Maybe they found a hawk baby and sold it to you!

He's 100% little man. While I disagree that all young cockerels naturally behave differently than pullets this early, that's simply his individual disposition. What a cutie!
