Gentle Handling Improves Baby Chick Welfare by Triggering Positive Emotions
To meet the high demand for chicken meat and eggs, nearly 30 million chicks are born daily in the United States alone. Alongside our insatiable appetite for animal products, concerns about animal welfare constantly accompany conversations.
Today, many farms are attempting to implement practices that reduce animal stress levels and improve their overall well-being. Although it is already known that early human interactions influence the behavior of farm animals, experts wanted to better understand how gentle handling affects animals on an emotional level.
Now researchers at the University of Bristol have shown that chicks actually benefit from gentle human interactions, triggering positive emotions. Their findings, published in Animal welfarehighlight how small gestures during early handling can have a significant impact on well-being.
“Our results show that gentle human touch can trigger positive emotions in young chicks,” study co-author Benjamin Lecorps of Bristol Veterinary School said in a press release. “The study demonstrates how simple, calm handling has the potential to transform the human-animal relationship from fearful to positive and, therefore, improve chick welfare.”

Animals clearly benefit from thoughtful handling
When it comes to animal welfare on farms, we don’t always think about how humans should directly interact with animals. However, it has long been observed that, for example, chickens’ early experiences with human owners can shape their behavior and productivity.
Previous research has shown that young broilers react less to stress during transport when they are handled gently. Chicks also appear to be negatively affected by being hung and exposed to transport noise, leading to poorer physiological outcomes.
Yet exactly how birds benefit from gentler handling and what this should look like in practice has not been fully understood.
Chicks and gentle human touch
To explore this, a team from Bristol Veterinary School exposed 20 chicks from a specific strain of laying hen to a so-called “conditioned location preference” test. Simply put, this type of neuroscientific test measures whether animals choose places they associate with pleasant experiences.
In this case, the chicks were introduced into two different chambers: one where they were handled very gently by humans who slowly stroked them and spoke softly, and another where the humans remained neutral by remaining silent and still.
After the conditioning sessions, the researchers observed that the chicks voluntarily chose the room where they had previously experienced gentle human contact. Interestingly, the chicks did not completely avoid the neutral room. The researchers interpret this as a sign that the chickens were genuinely attracted to the gentle handling environment, rather than simply avoiding a less pleasant environment.
How our behavior shapes animals’ early experiences
This study suggests that thoughtful human-animal interaction can have a measurable positive impact on poultry and that chickens may not be so different from our affectionate pets at home.
Research like this is crucial to understanding how good animal handling strategies can be helpful in mitigating negative early experiences in farm animals. The team hopes their findings will help inform future breeding practices and welfare assessment frameworks.
