Female snakes that are going through a breeding season tend not to eat at all. I began pairing my female with a het pied male in September. I didn't get a pre-lay shed until February 23rd, and didn't get eggs from her until May 4th. So it can take a long time. As soon as I gave her a week to rest, she ate a small meal and is now tossing back small rats like they are candy. I wouldn't worry too much. Akina went from September to the second week of May with no food. She was 1800g (right before I bred her and I also weighed her while she was gravid. She remained the same weight). After laying eggs she was 1300g. The eggs weighed 501g. So she lost 500g during the breeding season and that all went literally into making 500g worth of eggs. haha. I would not worry. Give her some time.
