I just brought home my baby Guinea pig 2 days ago. Not sure exactly how hold he is but my guess is he is 2-3 months. He started eating out of my hand an hour after being home, which I understand is quite fast. But is nervous when I go to pet him, jumps at any little noise I make and the 3 times I've had to pick him up he panicked alot. When should I start handling him and what's the best thing to keep him calm? I've had Guinea Pigs before but they had been previously owned and they were full grown so having a shy baby is new to me. I don't want to scare him.
