Dont take offence by this but I am not sure how to take that response :?
All my mice are housed well and seem happy, They always have plenty of food and fresh water their tubs are large so they have plenty of space and I keep them on wood shavings with hay for bedding and toilet roll inners to chew and play with.
The problem I have had with does culling babies seems to be down to one particular doe she culled 2 of her own litters and some of another does who she was in with.
