I've had my hatching eggs survive quite a bit of temperature variations, but 107 degrees is REALLY hot. If you have a candler, give them a week and see if they are developing. If you don't have a candler, buy one. It really helps to eliminate a lot of the work and time with eggs that are not developing anyway.
Other than extreme temperatures like you have, most eggs are pretty simple to hatch. I have 52 in my still air hova-bator that have been candled and are all developing nicely (I only threw away three eggs when I checked them). I have never monitored humidity, I just make sure there is always water in the bottom. I add warm water when it needs it. I turn the eggs myself, two or three times a day is enough. I don't wash eggs. They go in as they are, even messy ones.
The only trouble I've had with eggs is peafowl and emu eggs. They don't seem to make it through the mail alive. Chicken, duck, goose, quail, and guinea eggs are pretty tough.
Don't overthink the hatching. I'm not sure what went wrong the first time, but if your incubator is going up to 107 overnight, that is not good. I set my incubator up days in advance and don't add eggs until the temperature is holding at 99.5 for a while. Adjusting the temperature is the hardest part when you first set it up.
Keep trying, you will get it right. Nothing is more exciting than having them hatch!

> This is my second attempt at egg incubation. The first time was not successful. Since then, I have read more, and have more toys. I have a egg turner, a digital thermometer with hygrometer -so important! The little thermometers that come with the incubators are WAY off, at least mine are. I also rigged up a processor fan from an old pc for air circulation. So... I think I'm better prepared.

> I had a friend bring me a few eggs to try hatching with since I don't have a roo -predators took out my 2 beautiful roosters last year. From the time they were laid, until I got them in the incubator was about 4-5 hours in a vehicle, and that night the temps were about 35 degrees. Do you think that might have killed hatching chances -providing all else goes right? I did let the egg warm up before going into incubator. If that wasn't enough, over night, that same night after I went to bed, the temp went up to 107 with 62% humidity, I hope it was only for a few hours, 6 max. Did I completely destroy any chances of hatching anything?? I want to buy some nice stock eggs, and before I go spending any kind of money, I want to get the hatching down.
