Ditto Dat^^^I personally wouldn't eat them (has it been raining at all, any chance that those eggs got wet?) but if you're going to, check the outside shell to make sure there's no damage like cracks, chips, then once you crack them, if there's anything that seems off (any smell, anything that visually looks "wrong") I would toss them. As an extra safety precaution I'd cook these well, no sunny side up!
When in doubt....
Open eggs one at a time in a separate dish before adding to pan or recipe,
use your eyes, nose, and common sense to decide if egg is OK to eat.
Might time for some exams:I have only seen her interested in the laying boxes. She is the only one that will go back in the coop when they are all out free ranging. I have checked after she goes back in and found an egg. And since they were all under the slide unless she can get them from the woods to under there I don't think the other are laying.

Then:
Free range birds sometimes need to be 'trained'(or re-trained) to lay in the coop nests, especially new layers. Leaving them locked in the coop for a week or so can help 'home' them to lay in the coop nests. Fake eggs/golf balls in the nests can help 'show' them were to lay. They can be confined to coop and maybe run 24/7 for a few days to a week, provided you have adequate space and ventilation, or confine them at least until mid to late afternoon. You help them create a new habit and they will usually stick with it. ..at least for a good while, then repeat as necessary.
