Do I have a roo or two? And what breed?

Been perusing, and still can't tell.....bought these fluffy butts when they were a couple weeks old, the first week of June, 2013. Supposedly 'sexed', however, we've already had to get rid of a mean roo from the same bunch. We bought 7, and so far have had 1 confirmed roo....These two are very mild, not aggressive like the confirmed roo, BUT, their tail feathers make me wonder, and Raven (the one on the left) has a VERY deep voice, reminiscent of the roo we had to take back to the ranch. So, here we have Raven on the left, and Mamie on the right. Neither of them are aggressive...the tail feathers you see of the BO on the far right are hooked to the 'alpha' in our flock.

Also, as we were/are so new to chickens, we can't remember what breeds we got. These two I'm not sure of...

Anybody have any ideas? Thanks so much!!!

 

Yay! Thanks everyone!!!
