    Yeah, I know. They are a pain in the butt. But they pay the bills to keep my server running. Just a fact of life, I am afraid.

    Is that too much for me to ask of you to keep this site running? Well, sorry about that. I too wish I could get everything for free. But alas.....

    Google Adsense ad revenue for December, 2025 was just $30 over the cost of the lease for the server running this site. So, in effect, the money providing the incentive for me to continue running this site is coming SOLELY from the paid memberships and sponsorships here. Which honestly ain't much....

Still waiting for my first hatchlings...Any clue on how much longer I have?

Hey Everybody,

I haven't posted in a while, but have been reading to keep up with the times.

I have eggs that were laid on February 2nd, and they are definitly fertile (I've seen movement in both eggs, and the eggs are looking pretty large! They've been incubating at 79F, which I realise is a little on the low side, but I am trying my darndest to get females. Also, part of my logic comes from my crested experience, whereby temperatures that induce longer incubation produce larger babies. Today was day 68... this has been a long wait.

Does anybody have experience with incubation at this temperature, and how long it took? I'm incubating according to Albey's method to the "T".

Thanks for any input!

68 days is a long time to be in the egg but at those temps, it will take longer for a leo to fully develop.....

Believe me, it aint that hard to produce females.... At 83 degrees, your chances of producing mostly females are most likely the same as what you are incubating them at....

I do not think this has any baring on hatchling size.... Why are you trying to get larger hatchlings anyway??? Average size hatchling do just fine out of the egg....

I have no experience with this temp because it is risky incubating at that temp.... You say you are incubating at 79 degrees but nobody's incubator stays a flat temp all of the time..... What about temps fluctuating in an unfavorable direction (in this case, down)???

I am pretty certain you will get the very same results if you incubated in a safer zone rather than what you are incubating in now.....
 
Nicely put Gregg! ;)

I agree, it could be very dangerous for the hatchlings incubating at such a low temp. No matter at what temp there is no 100% quarantee of sex, so 80-83 would have been the safest route, and would not have taken so long. I would also think that were Leos come from that it may not even get that low of temp outside during breeding season, so it would be a very unnatural temp to incubate at.
 
Thanks for the input. The fluctuation on my incubator is +/-0.5F at the most (which I can tell by my digital thermometer's 24hr max/min values).

I will move the temps upwards, but what is the safest way, I've seen people increase by one degree F per day, with my incubator I can increase by 0.5F per day, perhaps that would be safer, and just bring it up to 83F over 8 days?

The whole thing about having bigger babies when they are in the egg longer is true for cresteds, the logic we've come to is that they have a longer time to fully absorb the yolk. I did have the best intentions, I figured the larger the baby, the healthier it would be, and the less likely it would be a premie. I now realise from what you've said that this is possibly not true for leos.

Thanks again,
 
A lot of people here will tell you that raising your temps mid incubation is not good. Tremper seems to be the only person that is for doing it. I would think that the eggs should be hatching very soon, and they have developed enough that rasing the temp maybe a degree or two would be ok, slowly. Someone else want to comment?
 
I incubated females at 80 last year and it took an average of 66.5 days.

My female hatchlings hatched out the same size and weigths as my males that were incubated at 89.5, the males just took less time to hatch, closer to 43 days.

Last year they took from 63 - 70 days, my temps did flux from 79.8 to 80.5, my first eggs this year were last month so no comparison yet.

Paul Sage posted a new hatchling a few weeks back that was incubated at 81 and took 62 days. (http://www.faunaclassifieds.com/forums/showthread.php?t=76778)
