Kilo, no, things didn't work out. I received her egg bound, calcium deficient, and "overweight," as diagnosed by an exotic animal vet just two weeks ago. The vet got the first two things correct, but was dead wrong on the last, as the cham was extremely
underweight.

Actually, "calcium deficient" sounds mild; while the cham did not have the visible gross abnormalities shown in the pics of the MBD info link, she was very deficient, not just a little. However, her severe underweight made her so weak she couldn't lay her eggs and she was no longer interested in eating much; the vet helped her lay some, but she just wasn't strong enough even though we tried force feeding to survive. It's possible she was older than anyone knew, too.
Still, it hurts.
Anyway, Tiffany, please do read that article and assess all your equipment and husbandry just in case your cham needs something more than it's getting. If your UVB is six months or more old, either have it checked for UVB output or get a new one, as the UVB output can decrease to the point of uselessness even though the bulb still produces lots of visible light.
Good luck!
