Do these look not dead?

By day 18 they should be almost dark all over. It's hard to tell fertility without cracking open an egg and looking for the bullseye. But I would not put those eggs into lockdown. If they have not developed, they could explode and then your incubator will be contaminated.

Were you candling in a dark room? What are you using for a thermometer? You might want to check that thermometer against a medical grade thermometer, as the calibration can vary by up to 5 degrees. That would make a huge difference. If you candled them in a dark room, I'm guessing that they did not develop, or were fertile. You might want to try a stronger light also.

I don't see any development in them either... or any indication that there ever was development. If they had started, and then died there would be blood rings, etc. here is a link to the page that I use for reference

The candling won't affect the hatch rate, especially if you are so close to hatch. It's possible that they either weren't fertile to start or they didn't settle long enough before being incubated. Keep us posted.

My guess is that the Post Office scrambled them. This is very common with shipped eggs. You can rule out fertile or not if you are willing to crack one open. Just look for the bullseye.

The room was dark and my thermometer was right and brand new. It was probably the post office. Thanks for all the replays I'll keep you posted.

I candled these four eggs today.... Are they alive? Its Day 18 of the 21 day hatch cycle.

None of those eggs look like they even developed, I would candle the rest and NOT put them in lockdown if they look the same..
There is no veining, no chick....They were probably not fertile.

I don't think you will be able to identify a bullseye after cooking the eggs for so long, it will just be a hot, soupy, runny mess!
You can always try, but I don't think even if they were fertile that they would still be visibly fertile at this point. I do believe you got a lot of infertile eggs, unless you find SOME signs of development in the remaining eggs. Even when eggs get scrambled in the mail, there is usually at least SOME percentage of successful growth/development.

I should have explained a little more:

If you crack it open and see the bullseye, then you know it was fertile but you have a cold spot in the your incubator (or the thermostat is way off).

If you see development but it stopped vey early on, then you know it was fertile but either bacteria or temp fluctuations caused it to stop and die.

If you see no development but a big mess, then the temp was either too hot and you cooked them or they were scrambled by the Post Office.

If you see no development and the structure is intact, then the egg was probably not fertile.

If you see advanced development (probably not likely with those images), then you either cooked it or it died from bacteria or some genetic defect.
