ResumoJULL (1932) points out that fertile eggs may be produced shortly after copulation and enumerates the number of hours elapsing from time of copulation to production of the first fertile egg as found by the following investigators: Gilbert (1905), 39 to 65 hours; Pearl and Surface (1909), 72; Coste and Gerk (1910), 28; Philips (1918), 23; Erickson (1924), 72; Fronda (1926), 20; and Dunn (1927), 21. Nicolaides (1934) found that the time elapsing between mating and the laying of the first fertile egg varied with different matings from 19.5 to 238 hours with an average of 66.2 hours. It was concluded that fertilization in the hen may occur in the upper end of the albumen-secreting portion of the oviduct. Waite (1911) secured 50 percent fertility on the third day and 70 percent fertility on the fourth day after mating. Maximum fertility was reported by Crew (1926) to have been reached . . .
