"A hen can lay only one egg in a day and will have some days when it does not lay an egg at all. The reason for this laying schedule relate to the hen reproductive system. A hen’s body begins forming an egg shortly after the previous egg is laid, and it takes 26 hours for an egg to form fully. So a hen will lay after and later each day. Because a hen’s reproductive system is a sensitive to light exposure, eventually the hen will lay too late in a day for its body to begin forming a new egg. The hen will then skip a day or more before laying again. See the related article discussing the reproductive tract of a chicken for more information on the specifics of egg production. Also, hens in a flock do not all begin to lay on exactly the same day, nor do they continue laying for the same length of time. Figure 1 shows a typical egg production curve for a flock. The flock comes into production quickly, peaks, and then slowly reduces the level of production."--Back cover
