I just recently got a guinea pig a week ago. He seemed to be adjusting well enough for the most part. Taking food from my hand, drinking, chuttering when I let him out for floor time. I am concerned though because he has been scratching a decent amount as well as grooming himself. He is young, but he jumps around a lot, I don’t think it is popcorning. He would come out of his hidey more often the first few days but now he just looks sad and scared in his home. He does have a bald patch on his body that I just noticed and he began wincing yesterday while i was holding and petting him in a specific spot. I am trying to find a vet to see him but I was wondering if anyone had any ideas if there is something wrong.
