I also lost two of the new colony babies today. I'm not sure what happened. Two two-week-old babies were out of the nest box (as they do hop in and out now), but both were in different places, and I thought both were dead. I picked them up and they both did the gasping thing. I knew they were too far gone, but I held them and comforted them as they passed. I hate losing animals. Now I'll be keeping an even closer eye on the other babies in there. They had food in their bowl, water in the container, and their nest box is accessible (if they hop out they can hop back in). We had some losses last litter too, and I'm suspecting perhaps one of the adults may be chasing babies. None are ever sick, they don't have diarrhea or sneeze, no goopy eyes, they're alert and well fed, active and healthy, and then during the day they just lay down and die. No injuries, no signs of trauma. I'm baffled. Last litter I watched Kin chase the babies around. Is it possible to chase them to death?
And of course, if I post a photo of Harry, I have to post one of Hermione too, right?
