i feeed both of mine in their enclosures...i use bar-b-que tongs and dangle them in by the tail and before i get them to the ground my snakes will have them...i was told it was better to feed in enclosre because of stress relations and if you reach in and take them out to put them in another enclosure to feed what's stopping them to think that everytime you go to take them out it's feeding time. i take a piece of the foil off the top that's pre-cut and place the mouse box on top of the cage for a few minutes then they start gettign active and come out of hide then i grab mouse with hand and use long tongs (prob 2 feet) to put them in....i watch untill there dead then feed the next ...
have fun MERRY CHRISTMAS!!
