On this side there is a caresheet for ball pythons. Check it out. U should put your baby in a ten gallon tank. What type of heat are u useing and what are u keeping your heat and humidity at? Pinkies are way to small. Even a just hatched baby bp can eat a hopper or rat pup. Clutter up his cage and put a hide in there for him so he feels secure and leave him alone for a week before trying to feed him again. He will eat when he's ready. If u feel there's something wrong with him a vet trip won't hurt. I don't know where u got him from but major pet stores like pet smart and petco don't take very good care of their animals.
