Thanks to pioneering work by researchers at Queen’s University Belfast, chickens are helping us understand animal behavior better than ever before. Picture a typical broiler chicken shed. Vast, bustling, and teeming with up to 28,000 near-identical chickens bred for their meat, these sheds are the epitome of efficient farming. However, this efficiency comes with a challenge: how can we understand the needs of individual birds in such a uniform crowd?

Traditionally, researchers either monitored a sample of birds, assuming they represent the whole flock or ran tests on a smaller pen hoping the results would scale up. However, these methods don’t capture how each bird uniquely interacts with their environment.

Enter the chicken backpack. With the help of Locatify, an Icelandic software company, the Queen’s University Belfast researchers developed a system using ultra-wideband tags commonly used to track objects in warehouses or people in office spaces. These tags were small enough to fit into custom-made chicken backpacks, allowing researchers to monitor each bird’s movement and location in real-time.

The results were astonishing. Despite the apparent uniformity of the broilers and their environment, individual birds showed remarkably different movement patterns. For instance, one bird spent most of its time within a ten-meter radius of its tagging spot, while another roamed around 97% of the house within a week.

Interestingly, the chicken’s activity levels didn’t simply correlate with weight or age. Some lighter chickens occupied less space than their heavier counterparts, and older birds still showed variable activity levels.

These findings challenge the assumption that broilers are a homogeneous bunch, suggesting that individual personality traits greatly influence their behavior. Bolder chickens might be more likely to explore, while the timider might move around to avoid farm staff or other birds. Some may have better spatial awareness, while others might be more social.

As we unravel these intricacies, we can begin to design interventions that cater not just to the flock as a whole but also to the unique needs of each bird. The knowledge garnered from these backpack-wearing chickens could pave the way for more nuanced animal welfare practices, creating a more sustainable and humane farming future.
