The mean of number of eggs per c1utch wa�19.5 ± 4.5 (range 8 to 31) and the mean incubation perlod was 77.4 ± 11.4 days (range 50 to 110 days). The mean hatching success was 89.6 ± 3.4 % (range 60.0 to 100 %). The mean early and mid embryonic mortality wa� 5.5 ± 4.3 %, the average late embryonic mortality was 8.5 ± 3.5 % and infertility 1.8 ± 1.0 %. |
