How often will my bearded dragon become gravid

Question
how often will my  three year old bearded dragon become gravid without a male?
she has not been in contact with another bearded dragon since she i bought her  three years ago.
She laid her  first lot of eggs January 2011 i think she had around 24 infertile eggs.(this is when  we found out my bearded dragon was actually a female)
i think she might be gravid again as she is temperamental,not eating and digging a lot.

Answer
Hello Samantha,
I am not a beardie expert but I will do my best to give you a thorough answer. I know they multi-clutch and can have 3-6 clutches from each mating. Usually they lay once a month during this multi-clutching. Since she has not been bred, I'm not sure how often she will lay but I would assume she would be capable of laying multiple times a year. Just make sure she has a good place to lay so she does not become egg bound. I hope this helps.
