Today I was out of the house for about 11 hours and when I came home the power was out! I don't know how long it had been but all the eggs in my incubator were cold. I know that it was long enough to drop the temperature from 100 to 70. I just want to know if it is still possible to hatch them. They have been in there for 4 days now but when I candled them I didn't see anything. Should I just toss them and start again or just go for it?
