In my experience, hedgehogs sometimes have to be "tricked" into eating a strange food.
Take their favorite food and crush a handful up in a blender or food processor. Then take a few cups of the new food and put it in a zipper bag or Tupperware container with the ground up old food and shake. Let it sit a few days and then try adding it to the kibble bowl.
