If you have young children, get rid of him, you are risking too much. And really it is not funny, it is scary as hell. If you leave him, he will probably be attacking you soon enough, and most definitely the children.
Totally agree. When I was a kid, we had a RIR roo that attacked us kids all the time. It was not funny. It was **** scary. We celebrated like mad the night we ate him!
