Chickenlittle, I too do not like snakes at all. I would have done exactly the same thing, even though I also subscribe to the "live and let live" concepts as a general rule. Intellectually, I know most non-poisonous snakes are good rat-catchers, but I also know they eat eggs and can get chicks, too. My first thought is for MY flock's safety. No, actually, my first thought is "AUUUUGGGGHH!!!! SNAKE!!! OMG!" as I run in the other direction. THEN I would think, oh NO, the chickens!!!
I hate spiders, but I only kill the poisonous ones. But I do not hate them as much as I am afraid of snakes.
It's all very well and good to be all nature-huggy and be one with the world, but if there was a snake in my coop, I doubt I would be willing to relocate it. Certainly not by myself; if my rescuer did it, fine - as long as it's a good mile or so away. I don't want it coming back for snacks.
