Well, I killed snake today too. A little garder sanke, maybe 2 feet. They are harmless but I have little chicks and it gave me the heeby jeebys. I don't care what people say about "not killing the snake that does no harm." Snakes scare me, always have since a little kid. To see one in MY chicken coop just forced me to kill it. I'm not damaging the population, we have plenty of them.
