A question that no doubt has occurred to many zoologists is that of the duration of fertility in fowls. The phases of that question included in this report are: the length of time elapsing from mating to laying of the first fertile egg, the length of time that a hen will lay fertile eggs from a single mating, and the effects of more than one mating on fertile production using the same male or two males of different breeds (cross breeding).
