I'd definitely be ready for them to get nastyI
Mine are all under a year old so they might change as they mature huh?

I've known some downright monstrous roosters. Couple as a kid that attacked us kids and my mom all the time. He went into the soup pot.
My parents had a barred rock roo that I would honestly compare to the Terminator. He would keep coming even after you'd knock the snot outta him. My mom was terrified of him and she is no pansy.
I have hatched out several bantam cochin roosters and hand raised them. Three out of the first four were just awful. The fourth is a total sweetheart and great with his girls. He is my current and only rooster.
