9 days is nothing! Leave him alone for 1 week! No handling or disburbing him! Usually it will take at least 2 weeks or up to a month before they settle in. Just keep repeating this weekly schedule until he eats! Once he eats then feed every 5 days! Don't stress! He will eat for you when HE is good and ready! I know for a new bp owner, it is very stessful when they won't eat but he will come around if due time! Good luck!
