The objective of this study was to examine the impact of using natural bio-organic supplements, varying cage heights, and different stocking densities on the egg-laying performance and egg quality of layer chickens at the Poultry Project for Layer Chicken of JRMSU- Tampilisan Campus in Zamboanga del Norte. The study involved 162 eight-month-old layer chickens divided into six groups and replicated thrice. These chickens were housed in cages of different heights and stocking densities to evaluate their impact on egg production and quality. The results demonstrated that providing chickens with fermented plant juice in their water, derived from madre de agua (Trichanthera gigantea), significantly influenced egg weight and resulted in higher returns above feed and supplement costs. Furthermore, maintaining the cages at a height of 3 feet proved optimal for egg weight. The number of birds in a cage also played a significant role, with four birds per cage affecting egg production and feed and water intake. Interestingly, cages housing three birds exhibited the best feed conversion ratio. Regarding egg quality, the natural supplements did not yield significant differences, but cage height influenced the weight of the eggshells, favoring the 3-foot height. Moreover, the number of birds in a cage impacted the thickness of the yolk. Overall, the study underscored the crucial role of natural supplements, cage height, and stocking density in achieving optimal egg production and quality from layer chickens.
