Prolonged storage of hatching Japanese quail eggs in the cool room at a temperature of 13-15 degree celsius, the eggs were subjected to the storage times of 1-4 days, 5-8 days, 9-12 days, 13-16 days, 17-20 days and 21-24 days revealed a highly significant decline in hatchability of stored eggs. Hatchability of fertile eggs were 81.42, 73.03, 70.12, 60.6, 43.16 and 25.25 %, respectively. Storage time also significantly affected embryo mortality attributable to time in storage. The embryo mortalities were 11.64, 13.86, 13.33, 17.21, 28.46 and 55.26 %, respectively. Althouth the storage times did not significantly affect percentage of delayed hatched eggs and death in shell eggs, percentage of the two characters increased with increased length of storage times. The death in shell eggs were 8.38, 9.34, 11.84, 11.68, 19.71 and 13.38 %, respectively. The delayed hatched eggs were 4.01, 3.78, 4.72, 7.42, 8.67 and 6.11 %, respectively. The result from this suggests that Japanese quail eggs should not be stored longer than twelve days before setting.
