My favorite sweetest friendliest roo who let me hold him and hand feed him and who came running for treats was also the roo that put a bullet sized hole in my calf when I wasn't looking.
That said, he went to freezer camp! I have little grand children and wasn't going to take the chance on him getting one of them.
Now the new flock has four roosters and I was trying to decide which two to keep. Leaning towards keeping the Jersey Giant until he charged a granddaughter last night. I kicked at him and chased him too, but if he doesn't get the message, He's out! I have two black cochins and a Buff orpington. Looks like I will keep the buff and one of the cochins.
My advice, once one attacks, give one kick/chase lesson, one chance after that. If he doesn't get the message...stew pot!
Also now my hubby uses the band saw to trim off the horn on my roosters....it's like trimming the dog's toenails.
