Wow those videos are sad.

It sounds to me like you believe this is happening due to a nutritional deficiency when they were young? Sometimes things like that can be at least partially corrected by proper diet and/or supplementation later. I know nothing about this species, so really the only thing I can recommend is to get them to a good herp vet.

I'm curious about the other picture in your photobucket. It looks like a frog and a BP? What is going on in that picture??
