Backyard chicken eggs are generally safe to eat. However, it’s in the handling that potential issues may occur. If an egg is improperly handled, it can be a carrier of diseases. In most cases, Salmonella infection is your biggest concern.
Chickens with the sole purpose of mass-producing eggs are typically housed indoors and rarely get exposed to sunlight as a means of protecting them from diseases.
The answer is simple: fresh eggs haven’t had time to break down. Like any natural food, eggs begin to degrade over time. The longer they sit, the more their texture, flavor, and nutrients change.
