Day 18...autoturner never worked.

If they were still alive in the second week, that is a good sign. Don't trash the eggs yet! The main reason why eggs are turned is to prevent the embryo from sticking to the wall of the egg in the early stages of incubation. In fact, some people even quit turning eggs at day 14 (I do not do this; I wait until day 17-18). You probably will not have as good a hatch rate as you would otherwise. Did you candle the eggs when they went into lockdown? Were they still moving? You may want to add "check turner" as a part of your incubation checklist in the future
Please update us with the results of your hatch! Hope you have a 4/4 hatch!!!!!! :)
