Yes, that's right. Once he's in his viv, by whatever means lol, he should be left alone for a MINIMUM of 3 day. A week is good to make sure the snake is settled in, although I personally leave them alone for 4 to 5 days.
After that period of time try the first feeding and begin handling the snake for short periods of time each avalable day. Work up from, say 10 minute handling sessions, and your snake should do great. Remember to not handle a snake for 48 hours (that number varies. some say 36, others 24) after feeding.
Good luck!
