I have two little female dumbos that are approximately 6 weeks old. One of them has a personality to die for but I've noticed that when she's asleep and I go into check on her she doesn't budge when she hears me. Her sister wakes right up but this girl is sound asleep. Today she didn't even budge when I touched her and I thought for sure she was dead or dying but after I rubbed her for a few seconds she popped right up and acted perfectly normal.

You think something is wrong with her or is she just a very sleepy baby?
