Royal Incubation temperatures

im thinking with longer incubation times more egg will be absorbed hence 90 gram egg which i usually get 75gram babies will be more like 85gram babies hopefully thats like two first meals :gj:

I shoot for 88 degree's but that's simply to allow for some swing in the temp of my bator. I've had them get as hot as 95 for over a day before and they hatched just fine. But I know guys that shoot for 90-91 but that doesn't make me comfortable.

I used a hovabator last 3 seasons at 89 and this year I built my own incubator and am using a Herpstat set at 89.7.

With the Hovabator they pipped at 52-54 days and were out of the egg by day 60. All hatchlings were between 75g-80g

I'm shooting for the same times this year with the Herpstat.

Last year I used an incubator for my JCP clutch but I also let my female ball maternally incubate hers. The incubator was set for 89F and the warm side of the tank my female ball was in fluctuated between 85 and 90 during the course of a day. This year I've got an incubator set up again at 89F and I'll just play it by ear with the snakes. If things are looking good, I'll let the moms maternally incubate but if anything looks amiss I'll put them into the incubator.

I set my incubator up for 88.5 this year, to allow for safe 2 degree temp swings.

Last year, I found no difference in hatch times between clutches incubated at 88 and 90. In fact, one of the 88F clutches hatched more quickly than most of the 90F clutches--and one of the 90F clutches hatched at 65 days.
I don't think temperatures are the primary factor in incubation time, oddly enough.
I have found that my clutches USUALLY pip around 55 days, and hatchlings are out before 60 days.

I don't have any eggs yet, but from talking to people at local shows 87-88 seems to be the trend. A local guy who had some amazing caramel albinos said he has reduced the number of kinked caramels by dropping the temps to 87.

At all the different temps has anyone had a swing one way or the other with the proportion of males to females? We were pretty much half and half last year (over 11 clutches) and we incubated at 89.

Really need an accurate thermometer to say for sure. We are only talking about a very small temperature range. With all the variation in thermometers that I have seen I would not rely on anyone's estimate of what they may have incubated at.

yeah i read about that on some magazine , bout turtle eggs hatching out males if its cooler temps , so i uped the temp on my incubator to 90 hoping i get all girls ... so far on the first clutch 2.2 , but i got more clutches to go
so we'll see....:bow::please:

91F... 1.9 so far:O
