There are many reasons why one of the babies might have passed including inappropriate development, malnutrition or Infectious disease. In case of the latter, you should clean the nest box with a dilute antiseptic solution and get the remaining babies (and mom and dad) to the veterinarian in case they too are ill and need treatment.
