We have never had this happen before, they like would just lay there... every now and then they would move. They would like make noises and extend out, it was VERY scary, all three of them died in my arms ( at different times) the first two died a day apart, and the last one died like 2 weeks later. There isn't a problem with the food because we have had numerous litters and this has never happened before. (We feed the moms and babies Purina show food, old fashioned oatmeal, and calf mana ( helps the mother get milk) and I give them plenty water.
