I have to disagree. Why not feed in the enclosure? What purpose does it serve to remove a snake from its enviroment just to feed it? If anything it will add to the stress level of the snake.
I don't understand how putting your hand in the tank would make your snake associate your hand as food. If anything, you going into the tank to get the snake out is associating the snake with feeding time. What happens when you get the snake out for other purposes? Will the snake think that every time it's being removed from its tank, it's going to get fed?
