Negative effects of prolonged egg storage on hatchability and chick quality may be caused by changes in the embryo or in the egg characteristics, or by both. The aim of this experiment was to investigate whether prestorage incubation (PSI), frequent warming during storage (FW), or hypercapnic incubation during the first 5 days of incubation (HI) affect egg characteristics, embryonic development, hatchability, and chick quality.
