A crossbreeding experiment involving reciprocal mating of Rhode Island Red (R) and White Leghorn (W) chickens was conducted to assess its influence on fertility and chick quality traits between purebred chickens and their hybrids. Result of the study revealed a poor clustering of genotypes based on fertility, hatchability, chicks quality and related traits. Eggs laid by R hens were heavier than those laid by W. Conversely, chicks hatched from W eggs were heavier (P<0.05) than those from R genotype, indicating higher chick yield and lower egg mass loss during incubation. Number of dead-in-shell chicks and weak chicks were higher (P<0.05) in the purebred chicks compared to hybrids, indicating a heterosis in the two traits. Crossbreeding therefore minimizes chick loss during incubation and improves chick quality.
