The present study was carried out to analyze the correlation estimates between various quality traits of backyard chicken eggs in Chmabar taluka of Tando Allahyar district. For this purpose, a total of one hundred fifty fresh eggs of indigenous backyard chickens were collected from various places. The birds were kept under an intensive type management system and were twenty-eight weeks of age. The results of our study observed for eggshell thickness (cm), egg yolk index (%), egg shape index (%), egg albumen index (%), egg length (cm), egg width (cm), egg albumen height (mm), egg albumen width (mm), egg yolk height (mm), egg yolk width (mm), egg haugh unit, and egg weight (g) were 0.381±0.003, 47.254±0.113, 77.003±0.176, 11.915±0.243, 6.001±0.017, 3.791±0.032, 7.001±0.013, 58.321±0.71, 15.647±0.981, 35.498±0.215, 79.657±0.764, 42.033±0.535, respectively. The results for correlation estimates among various egg quality traits ranged from highest positive to lowest negative for different traits under the study. It is concluded that indigenous chickens produce good quality eggs with better egg weight and shell thickness. It is suggested that if indigenous chickens are raised under better management conditions, they can produce better quality eggs in size and egg content compared with exotic breeds raised on expensive feed under controlled environment sheds.
