The experiment was carried out in three groups with total number of 2100 eggs. Eggs were incubated 24 h of complete darkness (G1); 24 h of complete LED lighting (G2); and 12 h of LED lighting then 12 h of darkness (G3). From the obtained results, there were no effects of LED lighting on hatchability percent and dead embryos. There were significant differences observed in chick performance among the three groups, chick weight at hatch was the heaviest in group of eggs exposed to complete LED lighting during incubation (G2) with high vitality percent.
