There's a "bowl test" you can use to see how fresh an egg really is. For the "bowl test," fill a bowl with water and drop the egg into it. If an egg is fresh, it will immediately sink to the bottom and lie flat on its side. As it begins to lose freshness, the egg will point toward the surface until the smaller end is no longer touching the bottom of the bowl. Discard the egg if it is completely floating in the water.
