How long have you had him? Wait at least a week before trying to feed him. If he dorsn't eat, don't keep trying to feed him it's only going to prolong the problem. Give him a minimum of a week between attempts to feed him. He's stressed and needs to chill out for a while. Feeding issues with BP's take a good deal of patience. My first one didn't eat for two months when I first got him. Then when winter came around he stopped eating again for 4 months. This is normal. As long as he isn't getting thin he's probably fine. Good luck!
