I would just try to wait her out. If she's not losing a lot of weight then you have time. One of my 2010s did the same thing shortly after I got her. She took a while to get started then only ate for a few weeks before she was back to not eating. After 2.5 months she finally decided to start eating again. Her total weight loss the entire time was 10g and I tried every trick in the book to get her to eat (even live ASF >__<). Some times they just don't want to eat and then suddenly they will start eating again.
