New pack of "weaned mice" to small

I picked up a 10 pack of "weaned mice" from an expo. I weighed a few and they're weighing about 10 - 12g, so more like hopper size. My corn is about 170 - 180g. Obviously these are much smaller than what she should be getting… Any suggestions on being able to still feed these off? Feed her more frequently… Feed her 2 at a time...??

I'd feed two at a time every 7 days to use them up and give you time to find real weanlings.

Sounds good. Thanks twolunger!
