Factors affecting hatchability of eggs at altitudes over 7,000 ft. are mentioned. Storage length of eggs prior to incubation was found to be critical and eggs collected up to three days gave best results. Recommended temperatures
are: first week, 102°F.; second week, 102-103° F.; third week. 103-104° F. and during hatching approximately 105° F. Relative humidity, especially during the dry periods,
needed special care and both by watering the floor twice daily and by using a fine spray (warm water) on the eggs, also twice daily, satisfactory results were obtained. Hatchability varied between 45-75 per cent of fertile eggs
candled at 14 days.
