Types of chicks. Hens or roosters?

[katydid360]

Hello
We are new to raising chickens and bought an assorted group. However we don't know how to identify them either type or gender. They are only a couple weeks old. Any help would be great.

This one I think may be a rooster

This one is showing a comb growth

This one is aggressive

First one does look like it could end up being a rooster, but all are too young to tell for sure. The middle one could be a buff Orpington, and the last one looks like a gold laced polish.

Thank you very much
