No, despite their unique and striking appearance, black chickens do not lay black eggs.
The Truth About Egg Color and Black Chickens
It's a common misconception, sometimes fueled by playful hoaxes, that chickens with black plumage, skin, or even bones produce black eggs. However, the color of a chicken's feathers or its internal pigmentation has no bearing on the color of the eggs it lays.
Ayam Cemani: A Case Study in Black and White
Perhaps the most famous example is the Ayam Cemani chicken, an exotic breed from Indonesia. These chickens are renowned for their hyperpigmentation (fibromelanosis), meaning they are entirely black—from their feathers and comb to their skin, muscles, and even their bones and internal organs. Yet, Ayam Cemani hens lay eggs with white shells. This fact debunks the myth directly and showcases that the eggshell color is a distinct genetic trait. Like the eggs of most black chicken breeds, Ayam Cemani eggs are typically white.
What Determines Eggshell Color?
Eggshell color is primarily determined by the hen's genetics and the specific pigments her body deposits on the egg during its formation in the oviduct, specifically in the uterus. These pigments are produced by the hen and are unrelated to her feather or skin color.
- Protoporphyrins: These pigments are responsible for brown hues.
- Biliverdin: This pigment gives eggs blue or green shades.
The specific combination and amount of these pigments dictate the final eggshell color. For instance, a hen that produces a high amount of protoporphyrins will lay brown eggs, while one producing biliverdin will lay blue or green eggs. If a hen produces no significant pigment, her eggs will be white.
Egg Colors from Popular Black Chicken Breeds
While black chickens don't lay black eggs, they can lay eggs in various colors, most commonly white or brown, depending on their breed. Here’s a look at some common black chicken breeds and the colors of their eggs:
| Chicken Breed | Feather Color | Typical Egg Color |
|---|---|---|
| Ayam Cemani | Black | White |
| Black Australorp | Black | Brown |
| Black Copper Marans | Black | Dark Brown |
| Black Orpington | Black | Light Brown |
| Minorca | Black | White |
| Black Cochin | Black | Light Brown |
As you can see, even chickens bred for dark brown eggs, like the Black Copper Marans, still produce varying shades of brown, not black.
Practical Insights on Egg Color
- No Natural Black Eggs: If you encounter an egg that appears black, it has almost certainly been dyed or painted for novelty purposes. There are no chicken breeds known to naturally lay black-shelled eggs. Practical jokers have even gone so far as to dye eggs black to "prove" that Ayam Cemani hens lay ebony shells.
- Inside Remains the Same: Regardless of the shell color—be it white, brown, blue, or green—the internal contents of a chicken egg (the yolk and albumen) are always the same, offering the same nutritional value.
- Genetics, Not Pigmentation: The key takeaway is that eggshell color is a genetic trait of the hen's breed, distinctly separate from the pigmentation of her feathers or skin.
