I know it has been quite some time since my original post but I just wanted to update everyone on my Jasper!
After reading all the responses, I decided to leave him alone(not handle him) until he fed 5 times successfully. Though several attempts were made to feed, he had no interest.
I bought a live male mouse to try scenting the frozen/thawed fuzzies. Had to return him because of the maintenance. Later bought 2 female mice to assist in scenting. I tried braining the F/T fuzzies. I was even trying to locate a feeder breeder in my area to find live fuzzies. Each feeding attempt was done in his viv. All with no success.
On JANUARY 19th he finally, completely unexpectedly, began eating regularly. I have since had him on a 5 day eating schedule. He has shed 3 times. Each one full, one piece and perfect! He now weighs 443grams and is 36in long!
He is a great eater! Since beginning to eat he hasn't ever denied food. Jasper is now eating 2 small rats each feeding. Reacts very well to handling, which is limited to once or twice a week.
I didn't change anything with his enclosure except for moving the thermostat probe to between the heater and glass. I have a lot of leaves and plants in his tank so I don't believe the size of the tank was the issue. I believe it was the stress of a new home and handling too soon/often that caused him not to eat.
thankfully I now have a fully functional ball python.
thanks again,
Nina
