Egg death temp

[Tommy13b]

I was wondering at what temp do leo eggs die, cold or hot it dosent matter, right now my incubater stays at around 82 for females, but i was wondering in case my power ever goes out.

 

[Tommy13b]

Anybody know?

I would say in general that getting below 79 would not be good for your eggs, but I read somewhere (can't remember where) about someone incubating at 76 that had hatches after a very long incubation period.

The Low is 75 you wouldn't want it to go to long at that temp and 95 is the lethal high I wouldn't cook at or above that temp for any extended period.
a safer bet is keep your incubators at between 77°- 93°

 

[Sidviciouser]

I have had the same eggs go from 71* and at a different time 105*. They were both for short period of time (hours), but they hatched out just fine. I don't think any of the eggs suffered seriously from this, but some are still hatching.

 

[Bandit2008]

So, if I've had 92 in the incubator for 5/6 hours isn't too bad?

I don't think that's a problem. I think 95 is considered the death zone.

 

[lillith]

What about 76* for about 8 hours?
Calamity struck, all was well at 90* this morning when I left, somehow my circuit breaker flipped during the day due to my stupid hot water heater freaking out (I have no hot water in the house until tomorrow).

I just got the incubator heating back up, it's around 80 and climbing...these eggs are almost 2 weeks old. These would be my first possible enigma eggs.

I guess all I can do is wait.............................*sigh*
I feel awful, I'm going for the water bag trick RIGHT NOW.

hmmmm well people complain about the hovabator but i have mine set in a closet and i get perf. temp lowest it's gotten is 84.3 and highest was 86 just once, i would try moving it into somewhere cooler than your main herp room, like a dark closet etc... taht way it doesnt' get very hot, unless you're workign witha non thermostat controlled one then i'd still move it to a cool place that stays a constant tempeprature and it'll be easier than in a main room where temps can flux so much.

 

[lillith]

Well, it's back to 90*. I guess I'll know in a week or two if they made it or not.
This never happened last year, I had perfect stable temperatures the whole two clutches I hatched (I know it's not much, but it was a good beginning, eh?).

reference book info

Ok, at risk of being moot, I found this in ye olde (1998) copy of The Leopard Gecko Manual (on page 74, article by Brian E. Viets, PhD):

"Duration of Incubation and Viable Incubation Temperatures

...(excerpt) In leopard geckos, the incubation period ranges from 36 days at 32.5*C (90.5*F) to 107 days at 24*C (75*F); longer incubation periods would be expected when incubation temperature varies. At 34* and 35*C (93-95*F), developmental rate slows, so the incubation period is actually longer. The lethal minimum constant incubation temperature for leopard geckos lies just below 24*C (75*F) and the lethal maximum constant incubation temperature lies just above 35*C (95*F)."

So I'm thinking I didn't kill my eggs, but now my question is: how likely are eyelid or tail (or worse) deformities from one gross fluctuation, in other breeders' experience?

Are there other threads for this?

 

[chachasushi]

Good question! I would say anything in the mid70's and below is getting iffy. If you're power goes out frequently, try to have a heat pack at all times as backup

 

[lillith]

It doesn't go out frequently, the heating element in my hot water heater for my house blew a fuse, my circuit breaker box flipped its switch, and it was the same one the outlet for the incubator was on. That's about as much of a fluke incident I could dream up to happen on a day while I'm at work...

I have since set up water bags in the incubator as a heat sink/stabilizer. I've also moved the incubator to a different plug that isn't on the same circuit on the water heater.

I feel like I should have somehow known or protected the eggs better, but it really was unforeseeable! Maybe if I can't give good advice here, I can be a bad example of what not to do. I don't have super-electrician experience, but would a surge protector on my incubator and/or water heater have possibly prevented this?

 

[NorCalNate]

Lillith, that same exact high temperature thing happened to me today. 2 eggs were just laid this morning and I the incubator was accidently set to 104F for about 5 hours. Do you think the eggs will still be ok? The temperature is now at 85F

 

[lillith]

You know, I don't have any experience with the high-end fluctuations...I know that those tend to be more dangerous. At least you caught it before it was all day long. My eggs have all hatched out so far, but I have one or two tail kinks, and one bebe gecko came out with a stubby tail. Other than that, my kids were okay.

All you can really do is wait and see and try not to chew your fingers raw.

Agreed!

Side note: This year I have hatched quite a few from the 92-93 degrees incubator, all female.

 

[Gregg M]

Personally, I would not go below 80 or above 90 with leo eggs... That is just my preference...

Eric, wouldn't you run the risk of producing super females from that temp?

 

[eric]

In theory Yes! But if you read the updated version on the "Hot females" They only tested for a year than later picked up the study and found different results on production of those so called "Hot females". We have keep all the females that were produced at that temp to watch how they develop.

yesterday i had a blackout, temperature in the incubator dropped from 87 to 72.5, the power were restored after a couple of hours, I ve in the incubator a couple of eggs 5 days old, what do you think?
