Aim: This study was carried out in order to determine the effects of storage length on the hatchability of ostrich eggs obtained from private ostrich farms.

Materials and Methods: The eggs, which were collected from ostriches in one season, lasting from March to September, were numbered, weighed, recorded with laying date and stored for 1-15 days. On the 14^th day of incubation, infertile eggs were determined and removed from incubation. On the 38^th day of incubation, eggs were weighed for the second time, and following weight losses measurement, the eggs were transferred to the hatching machine. The hatched chicks were weighed and hatchability of fertile egg, hatchability of egg set and chick weight results were determined.

Results: Average incubation period was 43.58 days. In terms of incubation period, differences between groups that were classified according to storage periods (short, medium and long) were significant (P<0.05). Average egg weight loss of during incubation was 13.70%. Mean hatchabilities of egg set and fertile egg were 57.90% and 75.00%, respectively and differences between the groups of storage period were statistically significant (P<0.05).

Conclusions: The storage period more than ten days has the potential to negatively affect the incubation results of ostrich eggs. So, it could be recommended that for storing ostrich eggs, 10 days of storage shouldn't be exceeded.
