He'll be fine. Just let him settle in for a week or until he eats for you and then start handling him for a few minutes at a time and up it from there. My ex never handled my bp before he gave him to me, either, and now Pablo doesn't seem to mind at all. It just takes patience and time. He might always be a shyer snake than your others or, after he realizes you aren't a threat, he might relax and stop being as head shy and flighty.
