No, way beyond not normal
definitely not normal, the fact that you are even asking is a little disconcerting. im all for posting info on cf and getting feedback or care suggestions, but there comes a time when you need to make a vet a priority and that cham definitely needs a vet now. since you have not filled out the help form, or provided any other info, all anyone can do is guess, if i had to guess, i would say that it is probably lighting related, i am guessing that it is something to do with some sort of powersun, mega-ray or cfl that was either not recomended to begin with or improperly setup. the only responsible recomendation anyone can make at this point is to turn off whatever uvb you are using (tonight) and see a vet first thing (tomorrow). in the meantime, better pics and filling out the help form in its entirety would be a good idea, all though i have my doubts as to whether it will make it even with vet care, EVEN STILL, MAKE IT OR NOT, IT STILL DESERVES A TRIP TO THE VET. jmo / edit ps can it still see, and what do you use for lighting?
