Need help identifying

[Arip89]

Hi everyone! New to hatching chicks. These 3 hatched out at the end of June. I know the black and white chick(barred rock) is a roo and I am almost positive that the all black one is a pullet but I am still trying to confirm this gray one. I believe it is a roo but it is not rooing like the other. Can anyone else confirm?
