I have been in the same situation. I love animals and could never imagine hurting one. After running out in the middle of the night on numerous occasions to try to save my terrified, screaming hens my mind has been changed. I have 2 hens left that now run to me when they see a predator. I have saved these two on two separate occasions in the last few weeks. Trust me, running out in the dark in the middle of the night knowing there is a predator out trying to make a meal out of my girls, when I know we have not only racoons, weasels, and opposums around but also bears, Bobcats, and who knows what else, is terrifying. I have done it. The whole time I am out there, in the dark, I know there could (and probably is) one of these predators only a few feet/yards from me as I search for my hens trying to save them from harm. At some point the switch flipped. Not only am I not willing to risk my hens to these predators, but I am also not willing to risk my life trying to protect them. So my thoughts on whether or not to kill a predator have changed. I know that if I am not willing to stop (kill) them then I must be willing to sacrifice my hens. And that is not something I am willing to do. The thought of killing an animal makes me sick. But so does the thought of having my animals, who expect me to protect them, get ripped apart. It is a line that gets drawn in the sand. I'm not saying that everyone should agree but just wanted to share what my thoughts/decision has been with you all.
