Too soon to tell, but none jump out as a roo. MPC is good about not sending roosters as warmers so I wouldn't worry, if they send extra it's extra of what you ordered and if you get a roo it's just a mistake in sexing (which happens from time to time).
The SLW looks very rooish to me and the whitee EE is a maybe. I would need to see both the tails on the RIR. Our roo had a little tail long after the girls had long tails. So the one on the left is maybe.
