The Ayam Cemani is a rare black chicken breed that originated in Indonesia (traditionally tied to Java) and is famous for its dramatic “all-black” look—feathers, face, comb, legs, and even dark pigmentation in many internal tissues. That deep coloring comes from a genetic trait called fibromelanosis (hyperpigmentation). Despite the rumors online, they do not lay black eggs; Cemani eggs are typically cream/tinted, and hens are usually moderate-to-lower producers (often around 1–2 eggs per week / roughly 80–120 per year, depending on the bird and season.If you’re breeding for that consistent, inky-black look, it’s worth knowing that pigmentation can vary in offspring. selective breeding matters!
