just wondering about an EE and upright tails

[pinksky]

I was curious about male vs. female traits. This is all still so new to me, so I have no idea if this is an obvious tell or not...but I have a 3 week old EE chick that has been displaying an upright tail. She is the only one that does this. see photo:

Is this a common male trait? Her sister (in back) doesn't do it:

Please tell me I'm just being paranoid and all chickens do this regardless of gender.

You're just paranoid!

Whew!
I'm such a newbie.

You just have to remember that EEs are a mix breed. There really isn't a standard. I have some that are shaped like orps, some that are more game-looking with long tails. That's one of the great things about them.
