Id wait more than 5 days balls can be very picky eaters so dont worry. A baby i just got recently has gave me trouble eating but now shes comfterble and i got her issues adressed and shes been eating good. I might half to be paitent with her like the other night she showed intrest in her f/t food but never struck but just kept on moving it around and gave her a little bump on the nose with it and she ate it, If they dont eat it can be agravating just give them time and they will eat for you. Just try and handle as less as possible until your snake starts eating good for you. Then your snake make eat right off. I got a adult ball after i adopted him nobody knew when the last time he been feed was (was droped off at the pet store) offered him a small rat a week later and he ate it. Stick with your little ball and its very rewarding watching them grow.
