Congrats you now have one of the pickiest eaters. It took mine three months to finally eat for me, and I tried everything, live, frozen thawed, exposing the brains, and force feeding. Just keep trying to feed it and don't give up. Offer a live rodent and watch the snake with it for as long as you can then remove it when it doesn't eat it (I wound up with a pet mouse doing this method). Never leave the snake alone with it's live food mice and rats like to nibble on snakes and cause harm. Try not to feed it in the same cage it lives in so it associates getting out with food, and it doesn't mistake you for food when you stick your hand in the cage. They make great pets and are very docile and sweet. Let me know if you have any questions, what I don't know I will research for you.
You should leave you're new pet in his new home for at least 5 days before handling him/her or feeding. Snakes are very nervous reptiles, and need time to adjust to the new environment. Make sure to have a hiding spot for him. Also check the temperature in the terarium. If it is too cold the snake will not eat because he needs the heat to properly digest his food. If the terarium is too large/small the snake will get nervous. When we drove from Ontario to Saskatchewan with my snake he would not eat for 2 weeks, which is perfectly normal. His entire world is shacking while he's in the vehicle. Also try feeding at night after the sun sets. Completely blacken his terarium so that there are no distractions. If he does not eat on the day the food is offered, wait 5day's -1 week before attempting to feed him again.
Well I'm sure you're right that he's just scared, but I have to tell you this story, oh and it's totally true too. This lady's husband went away to the army I think it was and they both had a pet snake, I think it might have been a python too but I honestly don't remember. Well, the lady was home alone with the snake and she didn't have her husband at home anymore so she let the snake out of his cage and allowed it to sleep in the bed with her. Well, the snake stopped eating and it seemed to be stretching. So she took it to a vet or something like that and the people told her that they couldn't let her take the snake back home because it was starving itself and stretching itself out every night next to her preparing itself to EAT HER! And I am TOTALLY not lying! She still wanted to keep the snake but the people told her that if she took it back home and it just so happened to escape from its cage, that it would've without-a-doubt eaten her. So be careful!
