    Will this destroy my chicks. They are due to hatch in one week. Lowered the temp back down by pulling the plug and cracking the lid just a bit so it would not drop way down,

    Are you using a still air or forced air incubator? That temperature is in the o.k. range for a still air, in a forced air a fraction too high, but not enough, IMO, and not for long enough, to do the embryos any harm. It takes awhile for the core temperature in the egg to rise, thankfully [​IMG]

    Actually it is the forced air incubator and I run it at 99.9 . But I am going to run the batch on out and see what I get with them. They are brown eggs (SLW) and hopefully the shells being a little thicker might have helpd also.

    I got about 16 chicks from 35 eggs and several had some feet issues that I am sure were caused from the heat. I am thinking that I may wind up with 10 healthy chicks. I have had three that had a stiff leg and I have had this in other chicks and I do not think it is a heat issue but I am not sure what causes it. I would sure like to know,
    I am going to do some more studying on the subject before setting anymore eggs.

    We just hatched 13 healthy chicks from several breeds and 36 eggs. We got 3 Marans, 3 Bielefelder, 3 Gold Laced Cochins, 1 Favorelle, and 3 Black Oprpingtons. This was my first attempt, my wife does this with her 2nd and 3rd grade classes but with less success.

    As I was researching it seems everyone has an opinion and it varies but I googled Chicken incubator university studies; there's tons of info. I read 103 was okay for some and if the temperature is 1 degree off (99.5 being perfect) it adds or subtracts 10.8 hours too or from the hatching time.

    We're pretty sure 99-100 was perfect but we had humidity issues and lost 5 in the hatching process.

    Congratulations and good luck, ours are 1 week old and a blast to watch.
