incubating temps

[malaysianbloods]

Hi everybody I was wondering if anybody know if it harms the ball eggs for the temps to fluctuate (spelling) between 88 to 90 and will the eggs die if the temps go to say 90.5 or 87.5.

Thanks for all the replys ahead of time.

No, I've hatched them between 86 and 91F... The more stable the better, but fluctuation within those limits will not likely cause any problems.
88 to 90F is the preferred target range.

Have a large sealed egg container with a deep egg medium. 4 to 6 inches
The greater the mass the longer it takes to heat up and cool down, therefore the more it tends to stabilize the temp

When you say between do you mean once you hatched them using the temp 86 and another time using the temp 91 or do you mean that your incubater varys from day to day from 86-91. Also did they all hatch out healthy with no problems.

Thanks for your reply more replys welcome.

I have a series of incubators, and was one of the first to start breeding Regius in the 80's. I did some clutches at 86 and another at 91 and most in between.... They all hatched. Another important thing to realize is that most commerical consumer grade electronic thermometers can't measure better than plus or minus 1 degree C which is nearly 2 degrees F. This means a reading of 90F might be 88 or 92. I think they're generally better than this but if you delve into it, you find that nearly all consumer electronic thermometers have a specified accuracy of plus/minus 1 degreeC which makes worrying about a degree or so, somewhat a moot point
Shoot for 86 to 90 and you'll be fine
Cooler temps result in longer hatch times.
At some point above and below these temps, there would be developemental problems such as kinking, but I can't say exactly at what temps this would occur.
I don't believe that slow fluctuations between 86 and 91 would be a problem either, but female Pythons generally do a good job of stabilizing temps, so we should do the same artificially.

thanks for all your help. That kind of puts my mind at ease. I'm hoping that are temp gun is working really well.
