Stargazing?

[Solomon]

I went to a pet shop near me, and they had 2 hatchling beardies - both of witch were stargazing(looking straight up) One of them would straighten up, walk a bit and fall on his side.

The owner of the shop asked me if I knew what was happening to them - I thought possilby MBD - and told her to get a MVB on them.

Am I correct thinking this is MBD? Anyone have an Idea as to what it may be?

Thanks for your help.
