Egg production generally takes place in confined or semiconfined housing systems depending on economic and environmental conditions. Although, there is a lot of liteture related to the effects of cage densinty and cage type on performance and egg quality parameters of laying hens, the influence of cage location and tier level is rarely considered. There are some studies related to the effect of various levels of tier level and cage location on laying performance and egg quality traits (Yildiz et al., 2006).
