A nice warm
bath and lots of food, probably a little extra calcium wouldn't hurt either. Did you not notice her getting bigger?? This is killin me!!! LOL!! I know mine is getting bigger, paid attention, made her a lay box, she dug her tunnel, over 2 months now and no eggs...then someone just ups and has eggs from their bearded dragon without ever even knowing she was gravid!UGGGGG!!
Anyway, yes they can lay infertile eggs!! Some lay more than one clutch, so watch her.
Seriously, had you made a lay box for her or anything? There is a thread in the breeding section about them laying eggs, it will help you out.
