What are your temps and humidity?
Are you using a UTH? Is it regulated?
How many hides do you have?
I'd give her a week before you try again. You could be stressing her by trying too often and stressed bp's don't like to eat. Also make sure that the mouse is the appropriate size.
So give her a week, and try at night. If she doesn't strike at it just leave it in the cage. I got my baby May 30th and went to feed her June 5th. I dangled the mouse and she perked her head up but didn't strike. I had been reading this forum, and read somewhere that a person left a mouse overnight. So I decided to do that, and came back 45 minutes later and the mouse was gone.
