As Gregg mentioned. Varanids do you put up with poor nesting. To make it clear, I did well with varanids because I had already developed and understood nesting with colubrids and pythons. I think I already explained, I developed deep nesting in the early seventies. I did so out of necessity, I had to be in the field collecting Alternas, when my alternas and other snakes were nesting. So I made cages with deep substrate so the snakes could nest while I was gone. That's when I learned they have more abilities that I thought. Previous to that we put in nesting 7 days after the shed. I kept the snakes in those deep cages and they nested the night after the shed. Again, early seventies. Since that time I have applied that concept to all manner of species, including live bearers.
ALso, Gregg mentioned, holding eggs can scar the oviducts and cause problems in the following years. And it often gets worse and worse until the female fails. Sir, this stuff is learned by doing it. And doing it over many many years. That you act like its theory is very odd. Its only theory to you.
