Have an egg that was laid on 7/17, is it over due or have they gone longer then this? It did develope a small dent here in the last week.
Thanks,
Robert

Hey Robert,

Sorry to hear about the tough luck you've been having with your glauerti... been there done that...lol

My glauerti eggs went bad at the 120 day mark(approximately). The babies still had some egg yolk in some cases, so I would imagine that they still had another week or more on their incubation.

There was a study done on incubation temps affecting incubation period. I believe the conclusion in that study was that lower temps(reasonable temps) resulted in longer incubation period, but the hatchlings were of a greater mass, and higher temps resulted in shorter incubation period, with smaller hatchlings.

I will try to dig up the abstract from my bookmarks... I forget where i placed it...

take care,

bob

Thanks Bob, also what were the clutch sizes you have recieved? So far mine are 11,9,1.CRAZY!!!
Thanks, Robert

Hi Bob, I remember reading that study, I as usual discarded it. The reason is simple, To few of clutches studied.

With experience, you will see lots of fluctuation. The reasons are not so simple of a few degrees either way.

The only defining remark I can make is, I get the feeling monitor eggs do not exsist in incubators in nature. They do not have proprotional digital thermostats, and they do have several kinds of natural fluctuations.

I have mentioned before, that the way we(in captivity) incubate reptile eggs is not similar to how they incubate in nature. While we do not have a problem hatching them. They(eggs in captivity) surely are more fragile and are less capable to fluctuation.

The reason I say this is again experience, I have seen reptile and monitor eggs in nature. They are exposed to far greater temperature and moisture fluctuations, then those in our "perfect" incubators. We have had eggs that were laid outside and missed(for various lenghts of time) occur nightime temps in the 20's, go completely underwater for extented periods, be exposed to very very high temps above 100F and still hatch. In fact, some eggs met up with all that and still hatched.

I would imagine, I could not have that happen in my incubators or incubator room.

Bob, I could go on and on, but I will end by asking you a few little questions. The first is, would you keep the potential parents of these eggs at a constant non-wavering temperature and humidity? The second is, with that in mind, why do you feel its important with their eggs?

Please understand, this is not bragging, but this year, we hatched in our little crappy losely controlled incubator room, snakes of several kinds, lizards of several kinds(including many species of varanids) several species of turtles and torts. All in one small room set up the exact same and set up very simple. With little or no maintenance and no substrate changing and that includes varanid eggs that went over a year incubating. Thanks FR
