No question and I don't care how big or small they are. Either you shoot them and they die relatively quickly or you leave them and they die a long, agonizing death at the hands of starvation or coyotes. I'd hate to be the one trying to saw them apart if one was still kicking; so if it was a one buck area I'd call a buddy to shoot the other (I'd even take the smaller one). Fair chase or not, it's just the right/humane thing to do.
Exactly Not sure about the smaller one part though.
