Sickness Behavior in Chickens (FS-1178)

As a prey species, chickens are stoic and typically suppress signs of weakness, including when they are sick. It is difficult to detect sick chickens because they rarely show signs of illness before it becomes severe. Chickens also instinctually hide sickness behavior in the presence of a perceived threat, such as humans, because such behavior tells predators that the ill chicken may be an easy meal (Figure 1; Tizard, 2008). While sickness is mainly associated with pathogenic disease, sickness behavior can also result from injury, nutrient deficiency, and environmental stressors, such as thermal stress.
