I rescued some birds this past weekend, and I have a few barred rock roos that are incredibly mean. By mean, I'm talking when I tried to pick one up to put him in the coop, because he was going to get blown away in a nasty storm, he grabbed a hold of my arm and wouldn't let go, even though I was trying to shake him off. When he finally let go, I disregarded it, and attempted again, got bit again, this time drawing blood. Now because these are rescues, I'm feeling a bit guilty for thinking of butchering them, but in my heart, I know that they are living a great life with plenty of room to run and plenty of food to eat, and that it is humane. So if I'm not incredibly crazy for doing so, how soon can I butcher. They are approx. 10-12 weeks.
