This study has been conducted to determine the effects of different cage densities on laying performance of white and brown hybrid layers during high summer temperatures. White layers, 60 weeks of age, were housed at a density of 3, 4 or 5 hens/cage (respectively 640, 480 and 384 cm2/hen), brown layers were housed at 3 or 4 hens/cage (respectively 640 and 480 cm2/hen). The results of present study indicated that housing at 3 or 4 hens/cage have not affected egg production and egg quality significantly. Increasing cage density to 5 hens/cage in white layers decreased egg production and Haugh Unit. However, it was observed that shell quality and egg weight were not affected significantly by higher cage density
