Some roosters are just nasty. But other than that there's hormones at play that will drive them to do certain things.I know how you feel, my Barred rock rooster is a mean one too, I have no idea why but that just seems to be the way he is..
Curious, did you hold and make real nice with your boy when he was young?
Glad to hear it! I didn't know they had a bad rep... but the girls are definitely bossy.I'm on my second hatchery barred rock rooster with no signs of aggression. The breed seems to have a bad reputation, but in my experiences they are the same as any other breed.
I agree that although some breeds do have tendencies... they ALL are individuals.
