5 treatments with 3 replications each, at 0, 45, 90, 135 and 180 degree respectively apart from normal egg position, had been designed for hatching Soft-shelled turtle eggs. Each replication contained 3 eggs. The transfer time to hatching box after laying had also done within 12 hrs, 24 hrs, 7 days, 15 days, 30 days and 45 days respectively. Eggs were incubated below sand level 5 cm, in which 40X60X25 cm stylofoam boxes with sand 15 cm in depth. It was found that there is no difference in hatching number, hatching rate and hatching time between 5 treatments (P0.05). And with the same result in transferring time (P0.05).
