2015 clutch surface temps of eggs..

[Albert Clark]

My 2015 dh clutch is sitting at day 51 today. Since day 48 I have noticed excessive dimpling in the eggs and no real movement. Also, the surface temperature of the eggs varies between 91.0f and 92.0f depending on which egg I point the ir gun at. The incubation temp has been at 88.5f - 89.7f with the humidity at 99%. Both tubs are covered with press and seal with lids. If the incubation temp is 88f - 89.7f why would the surface temps of the eggs be 91f -92f?? I have seen good veins in all the eggs but got concerned about the egg surface temps as well as the excessive dimpling. Thanks for your opinions.

In the last couple weeks of incubation, the eggs will generate their own heat. This is why you will see more condensation build-up during this time. Don't worry about surface temps as long as your incubator temp is fine.

Thanks Eric, I was told that surface temps by ir gun are not reliable that you should really use a thermocoupler device for that type of accuracy on egg temperatures. IDK, but it was a bit scary. Thanks again.

What were the egg temps early on?

Has Eric mentionned eggs generate their own heat the further along the more heat is generated.

This is one of the reason why I incubate at lower temps.

As you are in the last stretch you can probably remove the press n seal now and just keep the lids on. At this stage they should probably have more air exchange. It might help with the temps as well.

This morning was the first time I checked the surface temps on the eggs. Only did it bc I knew day 52 was a good time to check it. Thank you b for the response.

Yes, Eric did mention that the eggs generate more heat as they near the hatch date but the incubation temp is what is important. Thanks for the help.

Thank you rid, I did do that this morning. Hope it helps. Do you think the 91f - 92f surface temp by the ir gun may be accurate for the surface of the eggs?

To be honest, I have never measured the surface temp of an egg, but a couple/few degrees difference wouldn't surprise me. I figured I could get temps off the tub side or substrate and that would tell me enough. Also there is a small animal with new eyes in there and I just didn't want to take the chance that I was hitting the egg right where the eye could be. I am probably overly cautious/paranoid compared to others.

I have also started incubating at 87 degrees this year rather than 89 as I have in the past. The thought was that if I had a fluctuation I hoped it wouldn't spike too hot. I think the embryos are more susceptible to abnormalities from high temp spikes versus low temp drops; not that either are optimal but given a choice. It takes a while longer to pip, but I don't cut either so it doesn't make a difference to me. Best of luck to you.

Thanks for all your help and I appreciate yours and everyone's input. It is all reassuring and maybe it's all the nervousness now that hatching is near. You triple check everything bc you feel or anticipate that something may go wrong. I know how you feel about the candling and other incubation issues bc I have seen and read your responses. Thanks for your insight and opinion. I don't cut either. I will update the community on my results.
