I have two female leopard geckos who from what I can tell they have never ovulated. It is around the time for ovulation and they show no signs of ovulating. I am giving them plenty of calcium and they are the right age. What is the issue?

I have a female leopard gecko that I bred with my male. I saw them breed and separated them into their own tanks. I read that she would lay her eggs 16 to 22 days after copulation. It is now the twenty eighth day and she still has not laid her eggs.I can see her eggs and I am providing her with a moist laying box. I am keeping her right beside my male and they can see each other could this be stressing her out.

I have a leopard gecko that is overweight. I need to put her on a diet. I was wondering if I should just not feed her, if I should feed her less than what than what I have been feeding her before I noticed, or feed her something entirely different. I have been feeding her 2 to 3 superstorms every other night. What should I do.
