Dark Brahma - roo or pullet?

[Sursin1]

Is this dark brahma above a roo? I just noticed this one have different coloring on the feathers than my other two which I know are definitely pullets (shown below)

The top one might be a rooster but it'd help to know the age of them

I'm leaning more towards it being a girl but it might be a boy since it looks bigger than the rest

They are about 6 weeks old

We shall see they are all 3 the same age but his coloring is much different than the other two.. he doesnt have the detailing that they do on their feathers and today he is getting a lot more black feathers

Brahma (besides buff I think) coloring can differ between chickens, especially if they are from hatcheries, I'd say watch the comb, cause Brahma hens typical take a long time to get their combs full sized, if you see that chicken comb growing fast, it's probably a boy, but from the picture the tail feathers look more rounded than pointed (although it's kinda hard to tell with that photo) and rounded tail feathers typically mean pullet
