Online published on 6 December, 2021. Abstract Investigations were conducted to study the effect of breed and egg weight on embryo mortality rate in large, medium and small sized eggs of chicken breeds. The study was conducted at poultry farm of SKN College of Agriculture, Jobner, Rajasthan. For the present study eggs were collected daily from sheds and stored at 21°C temperature. A total of 297 eggs of hatchable backyard strain for each breed were collected. These eggs were grouped into three egg size categories viz small (38–44 g), medium (45–52 g) and large (53–59 g). For both breeds, embryo mortality was highest in the large egg class followed by small and lowest in the medium egg class. Among breeds, higher mortality was recorded in Kuroiler as compared to Chabro. The study revealed that Chabro breed was best performing breed for doubling the farmers’ income.
