First you want the animal to settle in and adjust from the recent move. This may take from 2 days to 2 weeks depending on how many changes there are in the transition and how that particular snake reacts.
Second you want to get the animal feeding. If the snake is still stressed from the move it is very likely to not want to eat . This is where letting them get settled is important.
Finally you can start handling. Short sessions at first . That last thing you wanna do is stress the animal out to start the process all over.
Good Luck, Be patient, and Have Fun!
