“…"States" were all behaviors lasting more than 1 s (e.g., standing, resting, and locomotion), and "events" were those lasting <1 s (e.g., shaking, wing flapping and pecking). An event could also occur in "bouts" (a short period of intense activity of a specific behavior), but events within bouts were counted separately and individually (3,(43)(44)(45). For example, if an individual pecked 10 consecutive times, each peck was singly counted as an event, independent of the time interval between pecks.…”

Recent research on free-range chickens shows that individual behavioral differences may link to range use. However, most of these studies explored individual behavioral differences only at one time point or during a short time window, assessed differences when animals were out of their social group and home environment (barn and range), and in specific tests or situations. Therefore, it is yet unclear how different behaviors relate to range use and how consistent these behaviors are at the individual level. To fill this gap, we here aimed to describe the behavioral budget of slow-growing male broiler chickens (S757N) when in their social group and home environment during the whole rearing period (from the second week of life to the twelfth week, before slaughter), and to relate observed behavioral differences to range use. For this, we followed a sample of individuals in two flocks (n = 60 focal chickens out of 200 chickens per flock), over two seasons, during three periods: before range access (from 14 to 25 days old), during early range access (first weeks of range access, from 37 to 53 days old), and during late range access (last weeks of range access, from 63 to 87 days old). By the end of each period, individual tests of exploration and social motivation were also performed, measuring exploration/activity and sociability propensities. Our results show that foraging (i.e., pecking and scratching at the ground) was the only behavior that correlated to range use for all three rearing periods, independent of the season. Foraging was also the only behavior that showed within-individual consistency from an early age and across the three rearing periods. Foraging may, therefore, serve as a useful behavioral predictor of range use in free-range broiler chickens. Our study increases the knowledge of how behaviors develop and relate to each other in a domesticated and intensely selected species, and improves our understanding of the biology of free-range broiler chickens. These findings can, ultimately, serve as a foundation to increase range use and improve chicken welfare.

“…Some factors such as the age, sex (Sandi 2013 ) and personality can be linked with how stressful a situation is perceived and how that situation is dealt with (coping styles; Koolhaas et al 1999 ). Across taxa, ample evidence shows associations between personality traits such as boldness, exploration, activity, sociability on the one hand, and stress measures such as glucocorticoid level and anxiety-like behaviors on the other hand (Cockrem 2007 ; Martins et al 2011 ; Seltmann et al 2012 ; Clary et al 2014 ; Raynaud and Schradin 2014 ; Ferreira et al 2020 ). Assuming an inherent relationship between cognition and personality, these individual differences in sensitivity to stress may influence the way that stress influences cognitive performance.…”

Individual variation in cognition is being increasingly recognized as an important evolutionary force but contradictory results so far hamper a general understanding of consistency and association with other behaviors. Partly, this might be caused by external factors imposed by the design. Stress, for example, is known to influence cognition, with mild stress improving learning abilities, while strong or chronic stress impairs them. Also, there might be intraspecific variation in how stressful a given situation is perceived. We investigated two personality traits (stress coping and voluntary exploration), spatial learning with two mazes, and problem-solving in low- and high-stress tests with a group of 30 female wild mice (Mus musculus domesticus). For each test, perceived stress was assessed by measuring body temperature change with infrared thermography, a new non-invasive method that measures skin temperature as a proxy of changes in the sympathetic system activity. While spatial learning and problem-solving were found to be repeatable traits in mice in earlier studies, none of the learning measures were significantly repeatable between the two stress conditions in our study, indicating that the stress level impacts learning. We found correlations between learning and personality traits; however, they differed between the two stress conditions and between the cognitive tasks, suggesting that different mechanisms underlie these processes. These findings could explain some of the contradictory findings in the literature and argue for very careful design of cognitive test setups to draw evolutionary implications.

“…However, while some studies have found that subordinate animals exhibit higher baseline cortisol levels, many have also shown the opposite pattern, or no correlation at all (reviewed by Abbott et al, 2003;Anestis, 2010;Cavigelli & Caruso, 2015;Creel, 2001;Sapolsky, 2005). Furthermore, many studies have revealed nuanced associations between cortisol and dominance rank, and GC profiles can vary substantially among and even within populations and species (reviewed by Abbott et al, 2003;Anestis, 2010;Creel, 2001;Ferreira et al, 2018Ferreira et al, , 2020. Factors including the availability of social support (e.g., Schrock et al, 2019), stability of the dominance hierarchy, ecological conditions, and energetic constraints, as well as individual animal personality (Ferreira et al, 2018(Ferreira et al, , 2020, and the frequency and type of threats and aggression an individual receives, can interact with dominance variables.…”

Glucocorticoids (GCs) are hormones released in response to stressors and can provide insight into an organism's physiological well‐being. Experiencing chronic challenges to homeostasis is associated with significant deviations from baseline fecal GCs (fGCs) in many species, providing a noninvasive biomarker for assessing stress. In the group of free‐ranging Japanese macaques (Macaca fuscata) at the Awajishima Monkey Center in Japan, ~17% have congenital limb malformations. We collected 646 fecal samples from 27 females over three consecutive birth seasons (May–August) and analyzed them using enzyme immunoassay to extract fGCs. We explored the relationship between fGC levels and individual (physical impairment and reproductive status), social (dominance rank and availability of kin for social support), and ecological variables (exposure to potential predators, rainfall, and wild fruit availability). A disabled infant was associated significantly with higher fGC in the mother; however, physical impairment in adult females was not significantly related to fGC levels. Females with higher dominance rank had significantly lower fGC levels than lower ranking females. Other factors did not relate significantly to fGC. These results suggest that providing care that meets the support needs of disabled infants poses a physiological challenge for mothers and suggests that physically impaired adults are able to effectively compensate for their disabilities with behavioral plasticity. Once an individual with congenital limb malformations survives infancy through their mother's care, physical impairment does not appear to influence fGC values, while social variables like dominance rank significantly influenced cortisol values in free‐ranging female Japanese macaques.
