Honestly something that hatch on september 20th should not even have been sold to you so it is IMPERATIVE that you do this to a T https://ball-pythons.net/forums/show...-hatchling-101
If the animal hatched on the 20th it had it's first shed at best on the 30th and might have had a meal on the 1st, an animal should only be sold well started with at least 5 meals in him, this one may not even have one so you are dealing with something that is not well started.
