Both of you, welcome to BP.Net

Being as you are both new owners, and new to the site, Id recommend starting off by going over this ball python caresheet and making sure your husbandry is correct, as well as everything else surrounding ball pythons.

As far as sleeping during the day, balls are nocturnal (sleep during the day, wander around at night) if your BP is moving around during the day, its generally a sign of stress and bad husbandry (I.E. Incorrect heat/humidity, insufficient hides)

F/T varies widely on the snakes preference, one thing I can not stress enough is make sure the food is thawed completely and warm enough (Put it in hot water for a while to thaw then hit it with a blow dryer) most snakes wont take if its to cold (I know mine wont) also heat the head area more, so the snake strikes that end more instead of the tail (to encourage eating head first and not striking your hand, seeing as how you should be holding the prey by the tail)

Hope that helps
