Cages are generally constructed in varying tiers. Because there IS an unavoidable variation in light intensity among tiers in multitier cage systems, a balance is needed between providing sufficient light at the bottom tier and avoiding excessive light intensity at the top tier (Awoniyi, 2003). This could lead to compromised laying performance and egg weight because of variability in laying rate. Provision of homogeneous illumination to each tier is an Inevitable in semiconfined laying hen houses.
