See any Roos?

I'm talking about the jersey giants in particular, though I'd appreciate a heads up on the Orpingtons too. I actually want a roo and have one on order since these are supposed to be girls. Now a friend has a roo, who was supposed to be sure pullet, the same age and I'm tempted to take him instead but only if I don't already have one. The closer giant in the pictures has a little red behind her beak so I'm wondering. Any ideas? I can also try to grab them up close if anyone wants better pictures since the lighting is a little red to begin with.

Any guesses before I adopt a jersey roo?

How old are they? I don't see any obvious cockerels but they look a little too young to sex accurately
