Because of the problem of new young mothers killing and eating their own young, would there be an advantage to putting an older experienced mother in a new colony with young mice? I was thinking of taking a mother from a colony that is slowing down and adding her to a new grouping, adding all to a strange or different container. Than after a litter or two retire the old girl, leaving the new young ones to continue. I don't know if this would work or be a waste of time and effort??
