“…In the current study, resting behaviours including both resting and laying in hens housed in conventional cages were highly expressed compared to those of housed in furnished cages. Different from our statements, Li et al, (2016) observed no significant difference between hens housed in furnished cages and conventional cages. On the other hand Pohle andCheng, (2009), Meng et al, (2017) stated higher sitting activity in hens housed in conventional cages.…”

“…Similarly, Shimmura, et al, (2007) reported that, furnished cages do not have any influence in comfort behaviours. Unlike us Li et al, (2016) reported that furnished cages increased comfort behaviours. It is probably not enough that only the cages are furnished, the size of the cages is also influential.…”

“…Similarly Pohle and Chang (2009) also reported that the birds housed in furnished cages spent significantly more time for feeding than the birds housed in battery cages. However, there are some reports which also indicated that furnished cages do not affect eating behavior (Li et al, 2016). It is impossible to exactly explain why eating behaviors increased in furnished cages ın this study.…”

“…This report fit in the current study. Yet it must be taken into consideration that aggressive behaviours in furnished cages were related to cage size (Shimmura, et al, 2009), cage design (Li et al, 2016) or cage density (Appleby et al, 2002). The decrease of aggressive behaviours in birds housed in furnished cages was supposed to be due to two factors.…”

“…Because environmental changes have a significant effect on behavioral responses, one of the best ways to detect the effects of furnishing cages on hens is to monitor changes in behavior (Li et al, 2016). Indeed, many behaviors have been using as an indicator of stress and welfare.…”

The aim of the study is to investigate whether housing laying hens in furnished cages in post-stress adaptation period causes any changes in behaviors or not. Due to the affects of animal welfare on production performance, the relationship between behavioral changes and egg production has also been studied. In the present study, 22 weeks old, 32 laying hens were used. The hens were subjected to transport. The transport procedure, including loading and unloading took 8 hours. Just after the transportation, birds were randomly divided into two groups as furnished and conventional cages; each consists of two subgroups with 8 hens. It was ensured that the hens in subgroups were unfamiliar with each other to induce social stress. On the top of each cage, a camera was fixed and continuous recording was done for 24 hours for 6 days. The behavior of animals was scored by time sampling method. Eating, drinking, resting, preening, wing flapping, tail-wagging, stretching, ground-scratching, gentle pecking, stereotyped and aggressive pecking behaviors were scored. In addition, the locations of the hens were also determined in furnished cages. Frequency of eating, drinking and ground-scratching behaviours significantly increased, but tail-wagging behaviour tended to increase in hens housed in furnished cages. On the other hand, resting, stretching and aggressive pecking behaviours significantly decreased in hens housed in furnished cages. In addition, the use of perch and nest rate in furnished cages significantly increased from the second day. In the conclusion, cage furnishing improves some comfort behaviour such as ground-scratching and tail wagging and decreasing aggressive pecking in laying hens. Therefore, it would be beneficial to keep stress-exposed hens in furnished cages in the post-stress adaptation period.

Some believe that farm animals need to be kept in conditions that provide ‘natural’ aspects in the animal’s environment and, thus, provide the opportunity for the animals to perform their full ‘behavioural repertoire’. Captivity may restrict either behaviours that animals have instinctive, intrinsic propensities to perform whatever the environment or behaviours that are elicited by deficits in the animals’ environment. Behavioural restriction may also thwart general motivation to seek variety and/or avoid monotonous conditions. Appreciating whether an animal suffers if deprived of the opportunity to perform natural behaviour requires, first, an understanding of how the behaviour in question is elicited and controlled, the effects of early experience and genetics on the behaviour and the behaviour of the species in the wild, and, second, the behavioural, physiological and fitness effects of deprivation of the behaviour. Housing laying hens in conventional cages compromises their behavioural repertoire, such as nesting in a nest box, dust bathing, perching and foraging, and the present review focuses on the welfare implications if these natural behaviours are thwarted in modern poultry production. A floor space of <561 cm2/hen increases physiological stress, reduces egg production and increases mortality in laying hens. There is also evidence of behavioural restriction in terms of reduced wing stretching, leg stretching, tail wagging, locomotion, floor and object pecking and preening with floor space in the range of 542–750 cm2/hen. Preference and motivation research has indicated that laying hens value resources such as nest boxes for oviposition, substrates for foraging and dust bathing, and perches for roosting. However, there is no convincing evidence that deprivation of these resources results in physiological stress. Furthermore, apart from adverse effects of the absence of perches on bone strength, there is no evidence that deprivation of nest boxes, perches, and foraging and dust-bathing substrates results in reduction in fitness such as reduced egg production or health. Nevertheless, preference research has indicated that the opportunity to utilise these resources, particularly nest boxes, may elicit positive emotional states in laying hens. Therefore, it is important to understand both how motivated the animal is to choose an option or perform a behaviour as well as the consequences of depriving the animal of this opportunity.
