Moving from a feeding container to the home container is not a problem, even a few hours after the snake has eaten. Don't dangle it by the tail, be smooth and quick and you'll have no problems. This is true for babies up to snakes over 200 lbs. in my experience. Of course, you need to be sure the snake has been fed an adequate amount. Feeding a bigger snake a smaller meal, not satiating it, may lead to a hungry snake looking for more food.
The first time or two that you move the snake will be learning experiences for you both, but be patient and remember who's in charge (you're supposed to be).
