what temperature does the chicken embryo die?

[Tatianna]

OH NO!
I set my eggs last night.....woke up this morning and the temp was 101.5 and 102.5 in still air incubators....am I doomed?? They are still air incubators. It might have even went to 103. One of my thermometers reads a bit lighter....I'm heartbroken, two incubators. What temperature does the embryo die? I had my incubators set for 24 hours prior to setting the eggs and then overnight they increased.
Thanks for your help

Hi,

Don't give up hope just yet...there are varied opinions and sometimes it can be just luck of the draw...I spiked past 103* for a short period in the beginning and still got 6 out 7 to hatch during lock down...
Brinsea's website has an interesting article titled something to the effect of 'What if the Power Goes Out' and it will give you a guideline of when to start to worry and when to catch your breath and keep it moving.

Here's that Brinsea article...

Please check out the Learning Center as they have a ton of articles, threads, posts, etc. to help you with a successful hatch.

Best wishes,

I have a still air and I actually keep the temp around 102. once in a while it spikes to 103 but not for long. I usually get hatching starting about day 19 or 20. 101.5 is the perfect temp for a still air.

So should I increase the temp?

 

[Tatianna]

I had it set for 99.5

I had it set for 99.5

I have a Hova Bator still air... Like I said. I keep that temp at 101.5-102.5.. I am currently on day 14, my last hatch (last month) was a 100% hatch and they were all out and in the brooder by the morning of day 21 ... I borrowed a forced air incubator last spring to hatch turkeys, the temp for a forced air is 99.5 but still air is 101-102.... Double check the instructions for your incubator to make sure.

In still air incubators the air is stratified, the air at the top of the incubator therefor is warmer than the air at the bottom of the incubator. Most still air incubators therefor recommend a temperature of plus or minus 101 when measured at the tippy top of the eggshell. You want to achieve a Goldie Locks temperature where the egg is not to hot or to cool (most of the time) in other words a happy medium

Because the air inside of a forced air incubator circulates, the entire egg (top, bottom, sides and ends) is 'supposed' to be bathed in perfect 99.5 + or - degree air.

Personally I use a force air incubator or else a mama hen. For over 60 years I have been around chickens and as of yet I never met a mama hen with a little fan riveted onto her back side to stir up the air in her nest. Use which ever style of hatching device you are most comfortable with, just become knowledgeable about what is needed to get a good and a healthy hatch with the incubation device of your choice.
