What did you try offering her? The first year I did this, I offered my female a small rat and it was refused and I didn't offer her anything else until the eggs hatched. This year the same female took weanling rats without any hesitation. Scaling back in size definitely makes a difference.

Congrats on the successful clutch!

I'm still waiting for my latest four to leave their eggs. They're poking noses out now but don't seem to want to leave their eggs at all.
