I had a similar incident when I used to volunteer for WIRES in sydney.
super warm basking spot, quiet enclosure, towel over the front, chopped pinky rats ( they can eat quite good sized pieces, I used a pinky rat chopped into 4-6 pieces) and minimal disturbance... Don't try checking on them, they are prone to stress when they're so small. Just monitor them by how much food they eat. If they're kept warm and have a steady food source available, they will eat fairly continually (unless there's another health issue)...
Plenty of substrate and hides to help them feel safe and secure....
Best of luck to you on this and feel free to PM me if you need any other info or assistance.... Simon
