Behaviors such as feather pecking and cannibalism have resulted in several problems in the poultry industry. Owing to animal welfare concerns, the practice of beak trimming and use of cage systems have gradually reduced, and housing systems are currently being applied such as barn, floor, and aviary systems; however, the identification and control of feather peckers among many individuals is difficult in these systems. For this purpose, research is being conducted to observe the effect of improving the environment by providing various pecking materials. Our study investigated the environmental enhancing effects of providing pumice stone and alfalfa hay to laying hens in the aviary system. These materials were effective in improving egg production,maintaining health, and alleviating stress. The findings of this study could be useful in environmental management to improve the welfare of the poultry industry in the new rearing system.
