OK your first ball python lesson is that patience is more than a virtue it's a necessity! Your snake will eat, it will just take some time. Limit the handling, offer him a meal once a week at dusk and wait. Does he have a small hide, relatively the same size as he is when he is curled up in a ball (most small hides are too big for hatchlings) they should have a snug fit. If not, get him a deli cup or something that he almost completely fills up, this will make him feel nice and secure. Put the snake and his small hide in a small box, add mouse cover it up and wait. I don't use hoppers, they tend to be a bit hyper for the hesitant eaters, adult mice or rat pups usually work pretty well for this and by putting them in a small box together it keeps the snake from having to case down the mouse and keeps him within a good range to peek the snakes interest. I have a couple of hatchlings I have had for a couple of months that have just recently eaten, ironically they refused all attempts with live but eat frozen thawed like candy. I have one snake that will only eat in the dark, some that won't touch mice, some that wont touch rats, some live, some F/T. It's just something that you have to play around with. Personally - I have found that snakes that have been trained to hide eat are my worst feeders as adults, maybe just a coincidence maybe not. In the mean time, keep plenty of clean water available and keep an eye out, if he starts to get really lethargic, then you may have to assist feed him, but you still have pleanty of time to get him to eat. Keep trying. And remember, this is just the beginning, there will be hundreds more refused meals in this guys future!!!!
Good Luck!
