Hi this is my first post as a new guinea pig mummy. I'm a bit concerned about 1 of our little ones, a week ago she had fresh blood on her nose which we thought looked like she had scratched herself. The next day it looked like it had started to heal over. However 2 days later her fur started to come off and the pictures shows how it looks today. Is this a reaction from the scratch? Or could it be mites? Any advise would be very much appreciated. Thank you
