is chick behaviour indicative of sex?

I have 3 or 4 chicks that will flap their wings, bob up and down and try to jump on each other. It's really cute... but it also has me worrying that the ones doing this are roosters. Will pullets do this as well? Thanks!

All chicks do it. It's part of establishing the pecking order.

That is WONDERFUL news! Thank you!

They all do it some, especially flapping around and pecking, but I notice my little cockerels doing the jump on the back thing the most.
