How long can an egg survive without being incubated?

The lifespan of an unincubated egg depends on a few factors, but generally:

* Chicken eggs: Can last 3-5 weeks in the refrigerator at 40°F (4°C).

* Duck, goose, and other bird eggs: Typically have a slightly longer shelf life than chicken eggs, but refrigeration is still recommended.

* Room temperature: Unrefrigerated eggs can last 1-2 weeks at room temperature, but their quality will deteriorate faster.

Important factors affecting shelf life:

* Freshness: The fresher the egg, the longer it will last.

* Storage conditions: Refrigeration significantly extends the lifespan of eggs.

* Egg type: Some types of eggs (like duck eggs) have naturally thicker shells and are more resistant to spoilage.

Signs of a spoiled egg:

* Strong odor: A rotten or sulfurous smell.

* Discoloration: The yolk becomes darker or the white turns cloudy.

* Movement: The yolk moves freely or doesn't return to its original position.

It's always best to err on the side of caution and discard any eggs that show signs of spoilage.
