when you have your temp correct, and then you add 40 eggs, isn't it normal for the temp to drop? i think it is.. it takes a while to warm that mass up. it is not going to hurt it to run the first day at 96 degrees.. that is a heck of a lot warmer than the eggs were bfore you put them in there.. If the tempdoes not come back up after 24 hours, then MAYBE you want to adjust it.. I am betting that it will come back up to 99.5 on it's own.
