If I were raising meat birds, I'd want them mean. The meaner the better, then I'd feel no remorse about ending them.
I think maybe that's why broilers grow into such ugly birds, so the people paid to process them think they are doing the world a service. The last roo I killed was suffering from a bad winter and it was a mercy (in my opinion, not his). But he was also one of the big, ugly sex links still roaming the farm. My goal is to catch and remove all of those this spring.
My grandkids are often around on the weekends,,, mean birds can become a problem quickly,,,,,I want the kids to like the birds not fear them
