Help with New Baby Ball?

I got him on tueaday and I have a corn snake too and I fed the corn friday and he ate right away. I assume thats because he is a corn, but the little ball didn't want his meal. I tried giving him a pre killed rat pup because thats what the pet store gave me with him. He sniffed it and kept looking around. I tried leaving it in his tank over night and nothing. He is very active for a little guy. A lot more active then the two foot Ball I had before. He has been all over his cage climbing up the plants and all over his branches. His temps are good so I take it he just hasn't settled yet? Also probably a dumb move on my part but when I bought him I asked when he ate last and the store said they didn't feed them yet because they had just got them in so should I have NOT bought him?
Thanks

It will take at least a week for him to settle into his new surroundings. That means no handling, and have his tank in a low traffic area. BPs are shy and easily stressed and nervous. Be sure the temperature and humidity is correct and he has 2 tight fitting hides. Give him time. He will be ok.

Oh and if they had not fed him yet, he may never have had a pre killed or frozen/thawed rodent. Give him a week alone and try again. Be sure the rodent is very warm. Use hot water to thaw and warm it. If he won't eat in a week or 2, get back with us for more tricks to try.

By just got them in does that mean they were captive hatched babies? If so, they may not have shed yet, meaning he won't eat until after that.

my baby had no trouble eating but he wanted live. so i got him a live pinky mouse that was to small for him just to stimulate eating, then about 5 mins after gave him a f/t large fuzzy he took right away now he has no prob eating f/t after a couple trys.
also i recomend seperate tub for feeding so he knows what is going on when its time to feed
