I'm betting it's a corn snake. There are a couple ways to tell if its a copperhead. A copperhead has a vertical pupil whereas most harmless snakes in Ky have a round pupil. If getting face-to-face with the snake doesn't work, flip him over on his back. Most venomous snakes have a double row of scales on there underside after the anal plate. Harmless snakes have a single row of scales. Better yet, leave it alone and no one, including the snake, will get hurt.
