MBD in Hatchlings or something else?

[BlackDiamondGeckos]

Two of my hatchlings this year seem to have really weak bones. They are clutch mates. One was starting to show this about a week earlier than the other and now they are really small and light. I have never come across a case of MBD in any gecko so I wouldn't know how to classify what they have, but they are really weak. I have been hand feeding them and giving them calcium supplement, but they don't seem to be getting better. I will set up an appointment with the vet tomorrow, but does anyone know what this might be and/or how to combat it? Thanks

Dusting

Other than that, it could be a nuerological disorder. But the odds of this occuring in two diff leos in the same clutch is unlikely.
