any guesses if my white leghorn chick is a hen or roo?

[MACKSFLOCK]

This is my white leghorn, she hatched on the 21st June so she is 18days old.
It might be too early to tell but I don’t know what sex she is.
I've never hatched leghorns before so I don't know what signs to look out for to distinguish weather "she's" a Hen or a Roo.
Can any of you have a guess?

Cute chick! However, too early for me to tell.
Best,
Karen

Too young to say.

You're going to be looking for big red comb pretty early on, for a male.
