1. Introduction to Cage Free Egg Handling

Handling cage free eggs requires specialized equipment and careful management to address challenges unique to this production method. Since hens roam freely and eggs are often laid in nests or on the floor rather than confined cages, eggs may have higher risks of contamination, breakage, or quality variation if not managed properly.

Modern cage free egg handling systems aim to maintain egg quality, minimize losses, enhance operational efficiency, and comply with food safety standards. This article explores technical parameters, key features, advantages, applications, operating instructions, maintenance, troubleshooting, and frequently asked questions, providing a valuable resource for poultry producers, processors, and industry stakeholders.
