put a male in with her and don't let them lock, maybe a few hours. sometimes this will get a female feeding again. I would try mice instead of asf. asf take a lot longer to get to size for a female that large. if the male stimulates her, her feeding response should kick in. many of my females that only eat one type of rodents, will eat anything right before or the beginning of their breeding cycle. once on feed, a long thin female can put weight on quickly. if not give her the year off. good luck with her, don
