thats what i do pretty much in all my enclosures.
i prefer to feed inside the enclosure but others prefer feeding in seperate tubs. although i dont believe in feeding in a seperate tub you may want to continue to do so if the snake was consistently eating for you when you were feeding it that way.
its up to you though. before feeding day comes still try out what was said whether you decide to feed within his enclosure or in a seperate tub.
