This literature review gives information about important behaviour patterns concerning feeding, reproduction and dust bathing of laying hens kept in aviary systems. The behaviour of hens in aviaries is compared to the behaviour of hens living under "close to natural" conditions. Feeding behaviour can be performed to a great extent in aviaries. The same is true for nesting behaviour, while mating behaviour can only be shown in mixed flocks. Dust bathing behaviour in aviaries should be further investigated. Although a litter area is provided and therefore dust bathing is basically possible, further research is needed, to which amount dust bathing behaviour is performed and how it is influenced by composition and height of the dust bathing substrate. Feather pecking and cannibalism can cause more deaths in housing systems with large groups of birds than in cage systems. Considering these results and the results of a first paper dealing with social and resting behaviour, aviaries provide an environment, where hens can perform a large part of their species typical behaviour repertoire. Therefore, under the aspect of behaviour, for laying hens in aviaries the potential to experience good welfare can be evaluated as fairly high.
这篇文献综述提供了有关笼养系统中蛋鸡采食、繁殖和沙浴等重要行为模式的信息。将笼养母鸡的行为与生活在“接近自然”条件下的母鸡行为进行了比较。在笼养系统中，采食行为在很大程度上可以进行。筑巢行为也是如此，而交配行为只能在混合鸡群中表现出来。笼养系统中的沙浴行为应进一步研究。虽然提供了垫料区域，因此沙浴基本上是可行的，但仍需要进一步研究沙浴行为的执行量以及它如何受到沙浴基质的组成和高度的影响。与笼养系统相比，在大群饲养的鸡舍系统中，啄羽和同类相食可能导致更多死亡。考虑到这些结果以及第一篇关于社交和休息行为的论文结果，笼养系统提供了一个环境，母鸡可以在其中表现出很大一部分其典型的行为模式。因此，从行为角度来看，笼养蛋鸡体验良好福利的潜力可以被评估为相当高。
