Nah, you don't need to go to all that trouble if they are healthy snakes, especially if they are used to being handled. Even my hatchlings are handled after they eat and they've always eaten and digested just fine. I worry about the little girl I have to force feed sometimes but so far even after the stress of that ordeal she's done fine. They are much tougher than you think. Just be gentle when you do it and wait until their feeding mode has passed so you don't get bit.
