The aim of this study was to compare the monthly hen day egg production (HDEP %), egg weights, total egg mass and mortality of two commercial egg strains and the indigenous chicken with their inbred progenies. The results indicate significant (P<0.05, 0.01) inbreeding depression in the HDEP %, egg weight and total egg mass of the two commercial strains but not in the indigenous chicken. Brooding mortality was higher in the parents compared to their inbred progenies. The inbred progenies recorded higher mortality than the parents during the rearing and laying periods especially in the two commercial strains. It was concluded that the exotic commercial hybrid should not be used as breeders for the production of day old chicks for commercial egg production.
