You really need to check all the ball breeders web-sites, there are great tips there.
Does she have a place to hide, in the hot end and the cold end. limit the feeding to once a week. or once every 2 weeks, she needs time to settle down, no one should really expect a ball to feed for 2 weeks minimum when baught home, captive bred or not.
if she is in breeding mode, she might not want to feed now anyway.
is the rack in a busey place, peopl passing in front of it, looking into it, tv's, stereo's etc nearby.
mine fed 2 times after being here for a week, now she has refused 2 weeks food. no worries. feeding out of the cage is pointless because that alone stresses them, is her cage dark, and do you feed her at night.
let me know, and also go to the big and little guys web-sites, there is a ton of info there.
good luck
