This species has a monoxenous life cycle with the only definitive host as chickens; it is extremely host-specific.Acquired via fecal contamination of food and water (oral-fecal route), it undergoes endogenous merogony in the crypts of Lieberkuhn (intestinal ceca of chicken) and gametogony in epithelial cells of the small intestines.
Eimeria. Eimeria is a genus of apicomplexan parasites that includes various species capable of causing the disease coccidiosis in animals such as cattle, poultry and smaller ruminants including sheep and goats.

A complete life cycle requires 2–4 weeks. One defining feature of the species during developmental stage is the occurrence of a single egg in each egg capsule. The development of an egg embryo to a mature cysticercoid in its intermediate host requires 28 days after infection, but fully mature cysticercoid takes about 31–34 days.
