2 month old Bearded dragon acting a bit strange lately.

my bearded dragon terra is very friendly, but she is acting a bit strange lately. She will sometimes do a fast head shake and close her eyes when my hand is near her, i'm not really sure why though because she usually doesn't care when anyone goes near her. I have heard of head bobbing but this seems a bit different, i'm not sure what the problem may be. Also lately she has been turning a really dark color, and we assumed she was just wanting more food, because she ate probably the most I have ever seen her eat.

We feed her crickets everyday, and keep meal worms in a dish all day. on the weekend we will feed vegetables and fruit to her one day only. and i calcium coat crickets about twice a week. Should I take her into a vet to see how she is doing or have others had behavior like this.

Hi. You need to dust her food 5x a week with calcium and 2x a week with vitamins. Her shaking her head could be a sign of a calcium deficiency. Nix the meal worms those can cause impaction. Salads should be offered everyday. Here is a good site to go by beautifuldragons.com. Also can you give a rundown of his set up? Lights? Temps? How big is the enclosure?
