This study was conducted on 320 fertile eggs (52-55 gm of weight) of 34 weeks old breeding flock. These eggs were cleaned, fumigated and stored for 06 days at temperature of 16C and humidity 70-75%. Eggs were equally divided into four groups i.e. A, B, C, and D having 80 eggs in each group. The group A was considered as controlled. The eggs of groups B and D were pre heated before setting in incubator while Turning was carried out on the eggs of groups C and D. After incubation (21 days) the hatchability percentages of all the groups were 76%, 77%, 80%, and 82.5% for the groups A, B, C and D respectively. Turning and pre-heating of hatching eggs during holding period did not influence the hatchability percentages significantly (P�0.05). Turning during holding period was responsible for the significant differences(P�0.05) in day old chick weight, weight gain in first week of age and early mortality percentages (during incubation) and had no effects(P�0.05) on F. C. R during first and second week of age. Pre heating of hatching eggs before incubation had no effect (P�0.05) on day old chick weight, weight gain in first and second week of age, F. C. R in first and second week of age and early mortality percentages.
