The eggs don't have to be there to get MI information Kelly. They still think they are there and that's all that matters. As long as the snake still thinks she has eggs.....she will "incubate" them.

I too have done MI on a number of species and I've taken the eggs from the females and watched the very same behavior....with a number of species.

Again, I've watched all my females go through the "MI process" without the eggs even there.....and they don't not shiver....even when the temps are down to the low 70's. All the other animals I have...such as Carpets, etc... DO.
The BHPs and Woma....do not.

They do come out to bask, eat, defecate, etc.... and they will sit under the heat for a few hours to return to the eggs....BUT, they do not shiver once they go back.

I've been working with them for many years now.....maybe if you're that interested in them.....pick up a pair and see for yourself.
All I can tell you.... is the experience of keeping them and breeding them....for a good many years now.
Plus, I'm very good friends with 2 of the leading BHP researchers in Aussie.....neither one of them has made any notes about them Thermal regulating....and both these guys have 100's of hours in field research with them.
More than anybody to date.

Hell, you still hear people saying that Womas and BHPs don't have heat pits.....they do.
It was proven a few years ago....yet.....people still regurgitate the old info.

It was also discovered that they have venom glads.
