We typically imagine eggs as always being smooth and even, but sometimes, they come in speckled colors and even have bumps on them, creating an uneven surface or small protrusions on the shell. These bumps and speckles can be jarring to see if you’re expecting smoothness, and they may leave you wondering if the eggs are still good to eat.

Bumps on eggs are often caused by a condition known as "calcium spots," which occur when the egg has excess calcium, and do not affect the egg’s quality at all. However, these bumps can also be caused by infections, genetic mutations, or even damage to the eggshell during production or transportation, which renders them no good to eat.

Some chicken eggs also appear speckled, which can result from genetics as well as environmental factors like high amounts of calcium. Additionally, if an egg spins too slowly as it leaves the hen's oviduct or if her shell gland is defective, it can cause speckling or spots in the shell, which does not negatively impact the egg in terms of quality.

As long as the bumps or speckles on your eggs are not caused by infection, mutation, or damage, they will still be safe to eat. The best way to tell if your egg is good or bad is to crack it open and check for spots inside the shell, a bad odor, or a cloudy yolk — if it has any of these, throw it away.
