This happens to me with my setup. With each colony producing 100 mice a month some are bound to get eaten or killed from birthing.
Just be sure fresh water and food is available. Usually the eating of the pinkies is the mother due to being malnourished. When i notice a mother eating her young i toss in some lab blocks in her tub for her to eat that and no others are eaten for rest of the nursing.
