You said..."so i bought a baby veiled.. and turns out the kinks in its tail is MBD"...how do you know that's its MBD? Does it show any (other) signs of MBD? How old is it?
If it is MBD then I would recommend you take it to a vet where it can be treated. As was already said, any deformities that have happened already won't likely be reversed...but if corrected, the chameleon may be able to live a relatively normal life.
In the meantime, there is a liquid called calcium sandoz or calcium gluconate that you can give to the chameleon that is supposed to be absorbed into the chameleon's system better than the powdered supplements. You have to be careful with it though....its syrupy and hard for the chameleon to swallow. You want to make sure that it isn't aspirated.
You said..."im dusting the crickets daily"...with what?
