Kings snakes are the champs as eating posionous snakes. One snake I really love is the hognose snake. Many times it is mistaken for a copperhead cause their markings can be a bit similar. When you run up on one first they will raise up and spread their head to make themselves look vicious...it that does not work they will roll over and blow themselves up like they are dead. They dine only on frogs and are rear fanged...meaning they CANNOT bite. Their fangs are in the back of their mouth kinda like where out wisdom teeth are. I use to catch one every year and keep it as a pet during the summer and release it that fall. They name hognose is because the end of their nose turns up. They get maybe average a foot long maybe a little more. SO...don't kill these babies!!Good for you on the snake.....I've run into 3 eastern kings already this year. I usually only see 1 or 2 the entire year. I just take them over towards the woods behind the chicken run so they can take care of all the mice for me
