So i got a 1.2 group of mice 3 weeks ago. after about a week both females were showing signs of pregnancy. Then in about the 2nd week, one started getting smaller. so now(in the 3rd week) I have one giant female and one that is the same size as my male. She has very slight lumps on her sides, but not enough to be sure she is even pregnant. i see momma mouse taking food from little girl all the time, but it's always the goodies like sunflower seeds. I feed them 16% protein sow feed with pet store mouse food and pecans. they always have water. I've heard that mice can absorb their babies. Any ideas? thanks guys!
