Am I feeding the correct amount?

[Robertn22]

Hi, I recently weighed my baby and she's 411 grams.

i started feeding her 2 mice every 7 days @20-22grams each mouse, my let store only sells these mice and then jumps to small rats which aren't so snall
using the 15% rule it comes out to about 60 grams both mice are below what I should be feeding her, should I make it 3 mice?

Doesn't sound like you'd be wrong going up to 3.
