1. The float test: Fill a bowl with water and gently place the egg in it. If the egg sinks to the bottom and lays flat on its side, it is fresh. If it stands upright on the bottom, it is still good to eat but should be consumed soon. If it floats to the surface, it is no longer fresh and should be discarded.
2. The shake test: Hold the egg up to your ear and shake it gently. If you hear a sloshing sound, it is likely that the egg is old and the yolk has started to break down. Fresh eggs will not make any noise when shaken.
3. The candling test: Shine a bright light through the egg in a dark room. Fresh eggs will have a clear, well-defined yolk and white. If the egg appears cloudy or has dark spots, it may be old or spoiled.
4. The smell test: Crack the egg open and smell it. Fresh eggs should have little to no odor. If the egg smells bad or rotten, it is no longer fresh and should be discarded.
5. The appearance test: Examine the shell of the egg for any cracks or discoloration. Fresh eggs should have a clean, smooth shell. Any cracks or changes in color may indicate that the egg is old or contaminated.

1. Egg Float Test: - Fill a glass or bowl with cold, salted water (about 1 tablespoon of salt per cup of water). - Gently place the egg in the water. - A fresh egg will sink to the bottom and lie flat. - A slightly older egg will still sink but may stand upright. - A very old or spoiled egg will float to the surface.
2. Shake Test: - Hold the egg up to your ear and shake it gently. - Fresh eggs will not make any audible sounds. - Older eggs with a slightly loose yolk may produce a faint swishing sound. - Spoiled eggs will produce a loud, gurgling sound.
3. Egg Candling: - Hold the egg up to a bright light source in a darkened room. - A fresh egg will appear clear and translucent, with a small air bubble at the wide end. - Older eggs may have a cloudy or opaque appearance and a larger air bubble. - Spoiled eggs will appear dark and may have cracks or discolorations.
4. Smell Test: - Gently crack the egg into a bowl or plate. - A fresh egg will have no noticeable odor. - A slightly older egg may have a mild sulfur or sulfide smell. - A spoiled egg will have a strong, pungent odor.
5. Egg White Test: - Crack the egg into a clear glass or bowl. - Tilt the glass to let the egg white flow out. - A fresh egg will have a firm, rounded egg white that holds its shape. - Slightly older eggs may have a slightly runny egg white with a flatter shape. - Spoiled eggs will have a thin, watery egg white that may be discolored.
