Hi, I was wondering if this is something to be concerned about. I have a 2 year old Pink belly side neck pretty sure female and under a few of her scutes it has a brownish substance. A few of the scutes are a little lose around the area and she has been basking alot lately. The substance is kinda brownish feels hard to the touch and is under a few of the loose scutes. Any ideas what it is? Thank you!
