Trait in study was the egg weight, the percentage of egg shell, yolk and Albumin, and yolk index, albumin high, shell thickness and weight  of yolk and albumin. The results of the present study showed a significant increase (P≤0.05) in egg weight, shell weight, shell thickness, shell weight, yolk weight, yolk and yolk size of the duck eggs compared to other species, a significant increase (P≤0.05) in the percentage of albumin weight in domestic chicken eggs, no significant differences were observed in both the yolk and the white weight index between different groups of birds.
