Over half of the litter dead.

[Lord Sorril]

This mother most likely isn't a first time mom. She had 5 babies alive and 7 dead by the time I found the litter. Can anyone think of a reason why?

First 5 came out fine, #6 got stuck in the birthing canal and resulted in the remainder being born deceased.

Sometimes this is bad luck, sometimes this is due to the female being overweight and/or old.
