So last night my gecko shed for the first time since I got him. I know this because he has flaps of dead skin hanging off his face and front feet. I tried to pull the remaining skin off with my fingers, but he wasn't having it. He's young and skittish and runs pretty much every time something unusual happens. Should I be concerned that this skin is still there? He doesn't seem to have any interest in removing it. What do I do? I don't want to forcefully pick him up...
