Can you tell a chick's gender based on their behavior and posture?

The chick jumps and runs around a LOT with its wings spread. Their legs are pretty straight and it is taller compared to another chick.

Unfortunately no. Chick behavior is not indicative of sex.

"Maybe." Like when I'm choosing chicks (from a pullet bin) I avoid taking any that are confrontational or overly curious/friendly towards a hand reaching into the bin. I certainly can't prove those are accidental males, but I'd rather not take the chance when there's other chicks to choose from.

I think you can make a pretty good guess. Aggressive stance, less fear are male traits.
