I am after some scientific evidence that if breeding mice eat chalk that it limits the cannibalisation of newborn mice.

I have learned (through word of mouth and networking with others) that placing a piece of chalk (non toxic) in the breeding mice food hopper, that it helps limit the cannibalisation of newborns. We have done this over the years and the trend is that there is lower incidences of neonate loss.

Stress has been reduced as much as possible limiting who can enter the room, noise, not handling newborns, etc, etc. and they are in a normal conventional facility .

The question is…. Why does this work?
