Hello guys, so I recently started breeding mice. I have 1 colony nursing babies together .3 2 of the mothers died unexpectedly when the babies were at weaning age. Maybe try got sucked dry from te babies? Now the second question 6 of the babies have pased away gasping for air? Do you guys know why this could be happening? They have 100% ventilation water and food available at all time. I have no clue why any of this is happening. It has not happens before on othersonly these ones. Is it possible the mice got a disease and its spreading?
