I got my bp when he was 3 weeks old! It took him over 3 weeks before he started eating and it was a fuzzy mouse that got him eating. He would not have anything to do with a rat or mouse pinkie. Some only eat certain colour. Try to feed every 5 days, if he refuses wait five days then try again and no handling until he eats. Just completely leave him be inbetween feedings. Be patient, he will eat eventually. Good luck!
