Will pullets walk with tail upright?

[Bean15]

I have a 4.5-ish week old Copper Maran chick, and I was sure she was female until now. I can add photos later once I get some, but I was wondering what behaviours are seen in roos vs hens. This is my only Copper Maran chick so I don't have any others to compare her to, making her difficult to sex. She walks with her tail mostly upright, but only when running or looking around. she got feathers faster than the other chicks, but I heard females feather faster than males (??). her comb is still a peach color, and there's no red. I've noticed she's somewhat more vocal than my other chicks, but nothing too noticeable. One of the other chicks who has some pretty convincing roo traits will walk with almost a "strut". The Maran hasn't been showing much of that, but I'm not sure if different breeds have different traits when it comes to sexing. Sorry that I don't have photos right now, but can anyone guess at what she might be, or provide be with things I can look for that signify "she's" actually a "he"? Help!

I've had enough roosters come out of sexed batches, I'm really hoping it's a pullet!

There are some behavioral indicators of cockerel vs pullet, but a pullet who wants to be the dominant hen will also strut.
How they feather in doesn't indicate gender in marans.

It's perfectly normal for your BCM's tail to become upright with activity, whether male or female. Chicks will do this regardless of gender. If you're still concerned, feel free to post pictures!

Thank goodness. Here are some pictures. I've noticed all of the chicks walk with the tail somewhat up, but hers is longer than the others, making me think it's a cockerel. HOPEFULLY I'm wrong, since it looks like we already have another male in the batch.
Guess I have to keep my expectations low. hoping I have a hen here:

here's a look at the comb (I couldn't get her to sit still long enough to take a closer pic)

Thanks for any help!

At this age, they're way too young to reliably sex. So don't lose hope yet!!
