They should be just fine.
Wash thoroughly and refrigerate.
Open each one separately in a dish before adding to pan or recipe,
give a good look see and sniff before using.
If in doubt or uncomfortable, scramble up and feed them back to birds.
Lock birds up in coop and run to re-habituate to laying on coop nests.
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 3-4 days (or longer) 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 24/7 for a few days to a week, 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.
