Production of good-quality chicks is the prime objective of modern hatcheries in the world. One of the main genetic factor that affect the subsequent productivity of layer and broiler chicken is egg weight. Effect of egg size on post hatch performance of broiler chicks has an important economic impact. Though lot of work has been carried out on egg quality traits of established breeds, the information on varieties developed and being popularized for backyard farming in rural and tribal areas are limited. The detailed characterization of these breeds with respect to its egg production, hatchability and growth performance traits are generally International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 8 Number 08 (2019) Journal homepage: http://www.ijcmas.com An investigation was carried out to study the effect of strain and egg weight on chick’s weight in large, medium and small sized eggs of chicken strains. The study was conducted at poultry farm, SKN College of Agriculture, Jobner. A total of 297 eggs were collected and grouped into three egg size categories i.e. Small (38-44 g), medium (45-52 g) and large (53-59 g). For Kuroiler breed of chicken, the chick weight was found significantly higher in medium class (38.5 g) followed by small (34.3 g) and large (38.1g) egg classes. In the case of Chabro breed, it was significantly higher in medium (40.6 g) egg class followed by small (36.85 g) and large (40.3 g) egg classes. Chabro breed was better performer than Kuroiler breed for all three egg weight classes of eggs. The average weight of day old chick was increased in Chabro breed by1.7%, 2.03% and 2.15% for small, medium and large classes, respectively over Kuroiler breed.
