I got a small male pie recently, along with 3 others, and at least one had mites. So far they have not been to bad, I have only been able to find a couple here and there, and have sprayed them and their cages down a few times. Mites are a separate issue, but I mention it because it may be related to my actual question, as to what the discolored scales are that I am seeing now. They were not there when I got him, and now are getting worse. I don't know if it could be related to the treatment, or the mites directly, or something else.
