Hello, my neighbors recently moved and left this little guy behind because they couldn't take him with them. We took him in about a week ago. I am concerned because his shell is very brittle on the surface and there are large pieces of the scutes that are chipping off. We already have an appointment to see our herp vet this week to check this out, as well as a general check up. He is in quarantine away from our other tortoises for now too. I just wanted to know if anyone had any ideas as to what this might be so I can go into my appointment with some knowledge. Also can anyone verify what species he is? He kind of looks like a desert tortoise but his head and shell don't really look right, but not sure if he just has some deformities. I really appreciate any help or advice anyone has in advance!
