Should have been a little less solitary about a month ago. hahahahahahahahahahaha, get a male.
While the egg appears infertile, I would incubate it. Most other types of reptiles have had parthnogenic reproductive events. Its rumored with varanids, not I have not seen it. So Incubate those bad boys.
Now, a little rant. You are seeing exactly what I have seen. Healthy females lay eggs, period. You do not have to do anything special, like brumate, hibernate, photoperiod, etc. Simply health and food allows eggs to occur.
I say that because so many of the experts(so-called) say all this and that is needed. And they never recieve eggs from their females. I just find it odd, that expert methods of husbandry does not allow for eggs. And, non-expert husbandry does.
They so often use the excuse, but I do not put the male in with the female. Well, as you have seen, that is only a small detail and it surely does not prevent eggs from occuring. It may prevent hatching, but does not prevent the laying of eggs.
Now your starting to understand, why so many years ago I said, monitors are not seasonally induced breeders, but instead food induced breeders. As soon as females have enough energy to produce, they do, period. Thanks FR
