A total of 227 eggs were collected during summer 2013 from Isa Brown (IB), Bovan Brown (BB) and Potchefstroom Koekoek (PK) chickens for comparative study of internal and external egg quality traits under intensive and village production systems in East Shewa, Ethiopia. The data collected was analyzed using SPSS and significant differences in egg quality traits were compared using post hoc multiple comparisons. Average egg weight, Haugh Unit, shell thickness, yolk colour, albumen weight, yolk percent and yolk to albumin ratio of IB showed a significant difference (p<0.05) under intensive and village production systems. BB showed a statistical significant difference (p<0.05) for egg weight, yolk height, albumen height, yolk colour, Haugh Unit, shell thickness, yolk percent and albumen percent under intensive and village production systems. Further, average yolk height, yolk weight, yolk color, yolk percent and yolk to albumen ratio of PK revealed a significant difference under village and intensive production systems. The study revealed that even though the differences were observed in egg quality traits under intensive and extensive system, eggs produced from village were also found to be good quality.       Key words: Egg quality traits, exotic chicken, intensive and village production system.
