Im confused with my chicks behavior

[Jamiestrow]

Hi
Im sure this question has been asked a lot but im confused by chicken behavior.
Im a first time chicken owner and need advice as to why my three week old chicks seem to fight or maybe its play.
I take them out to their run a couple hrs a day, as long as the weather is nice, to get some fresh air. They run around and exercise their wings but then they start jumping at each other, like a kangaroo kick, chest bump and have stare downs. They dont cause injury and it doesn't last long but I wonder if its fighting could I possibly have all roosters!? (I have 6 assorted bantams- straight run) One of them actually lets out a little crowing sound after an encounter. Its very funny to watch them. It almost seems like play but I have no Idea. And all 6 of them do this!
Thanks in advance

The one that crows is a rooster. But the chest-bumping doesn't mean ALL of them are roosters...all chicks do this to figure out the pecking order - who's on top and who's on bottom. As long as blood isn't being drawn just let them do it...they are going to do it no matter what.

Thats what I was thinking. Thank you for your response. When will I be able to tell for sure? About what age?

Every batch of chicks I have raised does this. It is normal. I believe it is play as my current batch does a little chirp chase chickie dance

Around 2 months we can make a good educated guess. Although some breeds are "sex-linked" which means the girls and boys are different colors at hatch, which makes them easy identifiable.
