Green Anole-crooked neck

Question
Our Green Anole has been eating and drinking fine until the other day I came home and noticed his necked is crocked.  When he is sitting it looks like he has it turned up to look above him.  He has kept it this way night and day.  I have tried to read around to see what might be the problem the only thing I could find was a calcium deficiency; however, we do feed him store bought crickets.  In turn, we feed them a store bought cricket food.  It's suppose to provide all the essentials to them for the green anole. Could this still be it or any other suggestions?

Answer
 Anoles require high calcium to keep from getting MBD, so a calcium supplement coated on the crickets, like the first dozen per day is always a good idea.
 Store bought gutloads are not so good.  The best is from Cricketfood.com, but you can also make your own gutload that would be more nutritious than you could buy at a store but getting sugar free Cheerios or Total cereal and grinding it up, that plus a wet sponge will do for the crickets.
 The best calcium supplement is Repcal or Minerall,
 I also would suggest a visit to the vet to rule out a neurological disorder called "stargazing".
