One quail chick seems to be bullying another. Should I be worried?

My 4 quail are 4 weeks old and one of them has been a bit of a bully from day one, but lately it’s gotten worse. They’ve been picking on one in particular and not letting them eat. Chasing them off every time they go near the food. Is this normal or should I separate? I’m guessing two are female and two are male and one of the males is chasing the other off but I could be totally wrong.
I put the bully in a pen next to them and they all seem much more calm without him in there.

What species are they? different quail mature at different rates. So they could be males, but they may not. Also, how big is your setup? could you post a picture?

They’re Coturnix Quail. My set up is 4x3. I’ll send a pic shortly.

This one seems to be the problem.

I would separate it out. Probably cull it because you don't want an aggressive bird.
