So, when a hen lays an egg too late in the day, the next ovulation occurs the following day, and the hen has a day when it does not lay an egg. In chicken hens, ovulation usually occurs under normal daylight conditions and almost never after 3:00 p.m. Typically, about 30 to 75 minutes after a hen lays an egg, the ovary releases the next ovum. However, the female chicken reproductive system is sensitive to light exposure, especially the number of hours of light in a day. The total time a hen’s body takes to transform a yolk into a fully developed egg and lay that egg is about 25 to 26 hours. In the oviduct, glands secrete substances that form other parts of the egg, such as the albumen (egg white) and the shell. When an ovum (singular of ova) has matured, it is released from the ovary into the oviduct. The reproductive system of a chicken hen is made up of two parts: the ovary and the oviduct. Clutch size, as well as the number of clutches laid in a hen’s laying cycle, varies by species, but the principle is the same across species.Īn overview of the female chicken reproductive system helps explain why hens lay eggs in clutches. For commercial egg layers, clutch size is typically large. Clutch sizes are species- and breed-specific. After laying a clutch, a hen has a rest period of about a day or more and then lays another clutch. A clutch is a group of eggs laid by a hen on consecutive days. It is for this reason that eggs are so nutritious for humans. All the nutrients needed for an embryo to fully develop are provided in the egg before it is laid. Another reproductive strategy of birds is to produce offspring that develop outside the mother’s body in eggs. The amount of time that birds devote to caring for their offspring depends on whether they are precocial or altricial birds, with the latter requiring more post-hatch parental care. For most birds, these unique strategies include producing many offspring and tending to the needs of the offspring for only a short period of time. Being close to the bottom of the food chain, birds require unique strategies for reproducing that also allow them to retain the ability to fly. Other than birds of prey (such as hawks, eagles, and falcons), most birds are prey. The avian reproductive system is designed to accommodate the risks associated with being a bird. Jacquie Jacob, University of Kentuckyįor anyone interested in raising chickens for eggs, whether for eating or incubation, an understanding of the female avian reproductive system is essential for recognizing problems that may occur and taking action to correct them.
