Hi,
One point to consider.
You moved her only 2 days ago into a new enclosure. This alone could account for a missed feed.
Breeding can affect the appetite of some of them differently in my collection - it turned two girls into rat disposal machines and stopped one eating alltogether who had previously been a bucket.
You've only had her 30 days so if you do decide to pair her after that short of a quarantine I would definately remove the waterbowl while they are together.
I understand why you shortened it but it merits a little more caution with direct animal to animal contact I think.
Do you know what she was eating for the previous owners? Maybe they had a different feeding routine.
You might try an F/T small rat left in her tub overnight. Can't hurt.
