Title says it all. Its got a small patch under its lip that doesn't turn with the rest of it. it stays at the light gray stage, while the rest of it goes dark, (due to the dark coconut husks I'm told). It seems perfectly healthy, eats great. I actually hand feed It most of the time. Is this normal? or should I be worried. EDIT: about a minute after I posted, it croaked for the first time. Its a Cope's Gray!
