I'm 99% sure these guys are roosters. I feel so dumb, I pulled out the roosters at 7 weeks, and these guys looked like hens. So for the past months, I haven't had any thought that they might be roosters, until I heard crowing from the back yard last week! Any thought about breed?
I know the black one is a rooster, he's the crowing one. But the grey? He looks exactly like the other one, so I'm assuming rooster as well, unless you guys say otherwise.
