catmandoo,
Snakes have very dirty mouths, so you might take precautions to prevent infection if you haven't done so already.
A couple days ago I saw a black rat snake that had climbed up the side of my chicken house to get at a bird's nest. The birds attacked it, and it dropped off, but the next day the birds weren't going back to the nest, so I guess the snake got their chicks during the night.
