家禽对空间的不同使用可能会导致鸟类之间不必要的攻击性相互作用和干扰。更多地利用围栏墙壁附近的空间，导致鸟类聚集在周边地区，留下中心地区无人居住。这些开放区域为鸟类之间的攻击性相互作用提供了机会，而当鸟类进入和离开壁区域休息时，沿着沿着会发生高水平的干扰。本文研究了环境复杂性的增加对肉鸡攻击和干扰发生的影响。假设在围栏中心提供垂直面板，可以通过增加优质休息场所的数量和减少开放区域的数量来减少鸟类之间不必要的相互作用。实验包括三个覆盖处理（网格面板，框架面板和无覆盖）和两个组大小（80和110）。将由PVC管道构造的垂直面板定位在围栏中心，而在无覆盖物处理中的围栏中心是空的。干扰和侵略性的相互作用，记录在5分钟的连续焦点样本的180个焦点个人从1至6周龄。遮盖物的存在对攻击性互动的出现没有显著影响（P>0.05）。观察到攻击行为的围栏百分比受年龄的影响显著（P
Differential use of space by domestic fowl may contribute to unnecessary aggressive interactions and disturbances among birds. Greater use of space near pen walls results in aggregations of birds around peripheral regions, leaving central areas unoccupied. These open areas provide opportunities for aggressive interactions between birds, while high levels of disturbances occur along the periphery as birds enter and leave the wall region to rest. This paper investigates the effects of increased environmental complexity on the occurrence of aggression and disturbances among broiler chickens, It was hypothesized that the provision of vertical panels to pen centers would reduce unnecessary interactions between birds by increasing the number of quality resting places and decreasing the amount of open areas. The experiment consisted of three cover treatments (mesh panels, frame panels and no cover) and two group sizes (80 and 110). Vertical panels, constructed of PVC piping, were positioned in pen centers, while pen centers in no cover treatments were left empty. Disturbances and aggressive interactions were recorded during 5 min continuous focal samples of 180 focal individuals from 1 to 6 weeks of age. The presence of cover did not significantly influence the appearance of aggressive interactions (P>0.05). The percentage of pens with observed aggression was significantly affected by age (P
