BBS Ameraucana chicks hen or roo?

[Palooosh]

Hi there!

I have three 7-8 week old ameraucana chicks I wanna see what everyone thinks they are! I think the blue is a roo (my favorite) but I’m hoping not. Pretty confident the splash is a pulley, but unsure on the black.

Thanks!

The blue looks to be a cockerel, black looks to be a cockerel, splash is a pullet.
