Have a friend asking me for advice, shes had 2 mothers give birth, thinks the 3rd may possibly be pregnant as well. Should she separate the females from the other females? (I'm not sure if they will harm others babies or not) Already let her know to remove the (adult) boys. She would also like to upgrade their living space, I said may not be wise to disturb the nests or move them into a different cage for now with new borns. Suggested giving them a week or two and spot cleaning the cage but not the nests. Is there anything I've suggested wrong here? Been so long since I kept mice.
