If you do feed in a separate enclosure, at least wait until he gets it all the way down and resets his jaw. Once they start moving around, you should be ok. Don't just pick him up. try to scoop him up as gently as possible with both hands to support as much of his body as possible, so you don't put too much pressure on his stomach, then immediately place him back in his enclosure, and try to leave him alone for about 24-48 hours, unless you absolutely need to move him for cleaning up pee or something...
