Ball Python wont eat?

I bought a ball python 3 days ago from my sisters boyfriend who had just bought her 2 weeks before that... they told me they couldnt get her to eat an the guy they bought her from said she wont eat white mice.. I have a small brown rat(live) an I cant get her to strike.. she pokes it with her nose then the mouse nips at her an she backs away.. this is my first ball python.. she climbs around her tank at night and hides during the day like shes supposed to... she has just a little bit of skin around her (neck?) From her shedding.. has had it since I got her... oh shes about 4 ft. Long.. I dont see any signs of sickness she seems perfectly healthy.. just hasnt ate in 3 weeks an im alittle scared for her I dont know why she wont strike but the mouse definitely holds her attention.. I only try an feed her at night
