I did it. I butchered one of the roosters.
I picked him as first because he's the most dangerous. He's attacked my 9-year old daughter on numerous occasions. So many that we've armed her with a tennis racket when she goes outside alone so she can fend him off. He's also attacked other people's children and that's really not cool.
As he was a 14-month old rooster, he was thick skinned and rather tough.
I turned him into rooster and rice soup and pressure-canned it.
At least that's tasty!
