Depends on the weather, if they'd been rained on or exposed to freezing temps,
I wouldn't eat them....I would scramble them up and feed back to the birds tho.
Floating an egg will only tell you how old it might be.
It's really mostly a waste of time.
They float due to evaporation when older.
It will not tell you if an egg is 'good' or 'bad'.
Plus then you've wetted the egg so it should be thoroughly washed and refrigerated.
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.
@Sofi You might want to confine your birds for a week or two.
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.
