Is this a Roo or a pullet?

[Haillisl]

Hello! This is a True Blue and is about 6 weeks old. I’m having a hard time determining if it is a roo or a pullet. I am new to chickens.
I was told since the comb is lighter in color it is a hen? It is the second largest out of my other birds. Does anyone else have a way to tell?

Thank you in advance!

Welcome to BYC!

This is a tricky one, but I'm gonna say pullet for now.
That coloration is suspicious though...

Hello!

When you say “true blue”, what exactly do you mean by that? Whiting true blues shouldn’t have red like yours does… are you thinking of a different breed or am I thinking of the wrong one lol?

Like @Tookie said, it’s very tricky to tell the gender. I’m not going to say that I’m leaning more towards one or the other, because I honestly don’t know! Try updating with new pictures in a couple weeks or if you see any noticeable changes in appearance or behavior
