Ahh I should have qualified my bulb complaint better. There are some excelent bulbs out there but you won't find them at petco or petsmart or your local petstore or at least I never see them at any of those places here in my area. Maybe Nicole has a URL of where to order good bulbs. I still think that natural sunlight is best when possible. I admit, I use some crappy bulbs for my tort, iguana and bearded dragons but I live in Georgia and only have to use them for a few months per year and have never had a case of MBD pop up here. Some people think that putting the cage near a window where sunlight can shine through will give them proper UV exposure. It will not. Window glass filters out UV almost if not completely unless your windows were installed sometime before the beginning of the last century. This is why your carpet doesn't fade like it did in the early 1900s...and again...NO MORE GOLDFISH
How big were youre other turtles when you got them? It takes a pretty good while usually for deformities to surface visually and it is no surprise that if anything at all is out of whack it would show up on the one that's been there since it was a hatchling since whatever is wrong has probably been wrong all throughout it's early developmental days. Overall the diet seems really good. The bulb and/or water must be the problem. You might also consider a calcium supliment.
