Overview

Disease prevention is a core pillar of successful poultry farming—just as essential as proper housing, nutrition, and daily care. In laying-hen systems, illnesses can spread quickly, leading to reduced production, increased mortality, and significant financial losses. Many farms struggle not because of lack of effort, but because everyday risks—visitors, equipment, wild birds, or feed contamination—are often overlooked.

To help address these challenges, this guide introduces practical biosecurity principles and disease-prevention measures tailored specifically for laying hens. Since the FARMS Initiative Responsible Minimum Standards do not require detailed biosecurity protocols, this document uses the more comprehensive, science-based requirements of Certified Humane as a reference. It provides farmers with clear steps to meet international expectations while improving flock health and long-term operational resilience.

Disease prevention protects not only hen health—but also farm productivity, reputation, and income. This guide breaks down essential biosecurity practices into simple and actionable steps that any farm can apply, regardless of size or production system.

After reading, you will learn:

‍
• Core biosecurity principles and daily routines needed to reduce the risk of disease entering or spreading within your farm.
• Vaccination and preventive-medication protocols that support flock immunity and long-term health.
• Practical, welfare-focused measures that stabilize production, reduce losses, and strengthen the sustainability of your farming operation.

Read on to learn how consistent biosecurity and proactive disease management can protect your hens, improve farm resilience, and help your operation align with internationally recognized high-welfare standards.
