Main Reasons for Chicks Falling on Their Legs and Effective Prevention

The issue of chicks suddenly sitting on their legs and being unable to get up often raises concerns among poultry farm owners. Such behavior usually indicates a health disruption and requires immediate attention.

Why Are Broiler Breeds Most Affected?

Broilers exhibit significantly faster growth rates compared to other breeds. In the 1980s, they reached the standard slaughter weight by day 63, whereas today this figure is only 36–42 days. This rapid selection focuses on muscle mass gain, while the skeleton does not always adapt to these changes in time. As a result, the center of gravity in broilers shifts forward, making them less stable and prone to losing support towards the end of fattening.

Key Risk Factors

• Stocking Density. If there are more than 3–4 birds per square meter, they are more likely to get injured and suffer from lameness.
• Humidity and Poor Ventilation. High humidity and ammonia buildup irritate the skin, contributing to infections and inflammation on the legs.
• Lack of Health Monitoring and Prevention. Parasitic diseases, particularly mite infestations, can lead to serious complications. Regular check-ups and preventive measures help avoid infections.
• Inadequate Lighting. Without access to outdoor runs and insufficient artificial light (less than 14 hours per day), chicks experience slowed development, which can negatively affect their leg condition.
• Mechanical Injuries. Sharp objects, damaged flooring, or falls from high perches (the height should be limited to 90 cm) can result in serious injuries.

When problems with the legs arise, it is essential to thoroughly inspect the living environment: check the flooring, bedding, and ventilation. If wounds are found on the legs, they should be treated with antiseptics, and the injured bird should be temporarily separated. In cases of signs of rickets—such as stunted growth or limb deformities—be sure to consult a veterinarian, as self-treatment is not always effective.

“Maintaining the health of chicks begins with prevention: cleanliness in the coop, spacious housing, proper feeding, timely lighting, and attention to the physical condition of the birds—all significantly reduce the risk of leg problems.”
