Correct me if I'm wrong, but you don't even have any bps, so how would you know this??
Op, you don't need to move her to feed her. She was probably hungry and your bite was in response to that. Moving a hungry snake in feed mode is just asking to get bit. Stop moving her, and don't be afraid of her. Just make sure you don't smell like rat when you go to handle her. It is possible she was startled, but I'm going with feed related.
