Thanks everyone. I'm okay with one Roo (in fact I'm a little excited to see how big and pretty he gets). I had ordered 3 hens and they sent 4 so I'm not surprised if one turns out to be a boy.
Joining the new brahma mama club ;). I have 4 chicks, 6 weeks old. Supposed to be hens but one has me wondering. Any of these look like a Roo to those with more experience?
Here's a close up of it's comb (first two photos - same chick):
