2nd EDITION

Technical Handbook: Cage-free production systems for commercial egg laying hens

The second edition of this handbook serves as a guide on the behavioral profile inherent to laying hens.


Understanding this profile forms the basis for the early detection of challenges faced by the birds, as they often manifest issues through abnormal behaviors.


This material was created to provide readers with clear and educational information. We hope that it inspires readers to strive for improved welfare for laying hens and promotes more ethically sustainable production, resulting in higher quality cage-free eggs.


This work is the result of the MIRA Initiative Support Project (Research Incentive Grant 2023/2024), coordinated by Prof. Dr. Rosangela Poletto, PhD, with the collaboration of Elisabete De Marco, an Animal Science undergraduate student, and support from MSc. Caroline C. Mazocco and the Certified Humane® program.
