I locked down at 12:01...and the humidity FINALLY got up to 60 just now...I locked down with 50% and a new sponge added....

No shipped eggs in that bunch, they are all home grown Iowa Blues. I'm starting to worry my brooder will be overloaded by the first week.38 out of 40 go into lock down? Good job! Are they from your own flock...or by chance...shipped?!![]()
I need to find out how to get a thermal image off the camera. Eggs don't generate heat themselves. If they did they would self incubateChicks cant generate their own body temps for a while after they hatch hence why we have to give them heat or a hen keeps them warm. Out of 35+ thermal shots I've taken, I have never had eggs glowing hotter then anything else in the bator or hatcher. More then likely if your temps have gone up, you're a) most likely using a Styrofoam incubator, and b) your room temperature has increased. Best way to solve the problem is to go digital on the controller.

The embryos do generate heat, especially later in incubation when they are more developed. It's not enough for them to incubate themselves, but it is enough to raise the temperatures a degree or so late in incubation.
This is a quote from GQF, "About half way through incubation process, you will note that the temperature will be increasing and you will have to adjust thermostat down nearly one full turn. This is normal and is caused by the embryo forming into a chick and generating heat."
I've seen this in many sources and I believe I read that you can tell fertile from infertile eggs using thermal imaging because the infertile eggs will be cooler than the fertile eggs which are generating small amounts of heat.
I don't mean to start an argument, I just thought I'd share my side of the topic.
Quote: Thank you! I did think of that and stuck a glass thermometer in there yesterday. It says 99.5 while my digital says 99. (The digital only gives me whole numbers, and it has said 99-100 steady since the first couple days, except dropping a couple degrees when I would candle, but it goes up fairly quickly.) Next time I will try your idea, too.
The other thing I thought of the last couple days, is that I lined the bottom of my bator with aluminum foil. Could that cause a problem? I wouldn't have thought so at such low temps. It is just plain old foil.
So, next time I am only going to candle 2x. I am glad I did watch them so much this time, though, as I learned a lot, and feel a lot more confident about when they are doing well, if they didn't develop, if they died, ect.
No foil in the bator.
use 2 thermometers.
I think I will also get myself a turner, so they get turned more often, and so I won't be opening the incubator so much
Here is my lone egg going into lockdown. (Thank you Sally for posting the basket idea! It solved that issue for me.)
I found someone who has chicks that are less than a week old. I am trying to decide if I should pick them up now, or wait and see if it hatches. It will have to be alone a couple days anyway, until it is old enough to be put in with the older chicks. The place is an hour away though, and I am going through there today.
