So, after reducing the run size and not letting him out to run around its getting worse. Soaked him in Epson salt for about a half hour, he actually went to sleep! Any way, inspected again and did not see anything obvious, no bubble foot or cuts. He did not show any sings of being hurt when I squeezed, gently but firmly, his foot and leg. The dark spots on the "scales" has been there since he hatched and has them on both feet . Thanks for the help, have a video but can not get it to load.
