male or female?

Hello everyone, I'm new to this whole chicken thing. We hatched some eggs in our classroom and I decided to keep two of the chick's, depending on if they are male or female as I live in town. They are 3 weeks old and I'm unsure of the breed. Can anyone help me out with these pictures?

The white one maybe a Plymouth rock, they are to young to say for sure but I pretty sure they are cockerels.

Thank you! At what age is it easier to tell what they might be?

At least 6 weeks, sometimes older.
