The Effect of Hatcher and Setter Humidities on the Hatchability of Bobwhite Quail Eggs

Abstract

Five replicate experiments were conducted to determine the optimum humidity for bobwhite quail eggs during incubation (Days 1 to 21: setter humidity; and Days 21 to hatching: hatcher humidity). Three wet-bulb temperatures (80, 86, and 92°F) were used during both periods. There were no interactions between humidities used during either period. Results varied considerably among experiments. Hatchability was slightly higher when humidity was above 80°F wet-bulb in both setters and hatchers. Previous recommendations of 86°F wet-bulb for setters and 92°F wet-bulb for hatchers appear to be satisfactory.
