Sad looking guinea pig

Question
I adopted a baby guinea pig about 2 weeks ago. She is 1 month old. She seems to be very shy and jumps at every noise. She seem to be doing OK but yesterday I noticed she put her head down when she rested (which looked like a napping cat). I think this is abnormal but other than that she seems normal. She eats and drinks quite well. Is this a sign of sickness or depression? Is there anything I can do to help her? Thanks for any advice you can give.

Answer
What do you mean put her head down. my gp's sprawl out all the time to sleep or just lay all the way down, if that's the case she is fine. You shouldn't worry unless she can't get up or something like that, not if she is just resting. She should be fine. IF you still suspect something trust your gut and take her to a vet....
