虽然它们对福利有许多缺点，包括行为，但蛋鸡笼也有好处。例如，攻击性和同类相食（或需要修剪喙以防止这些）通常比其他系统少，对鸟类和生产者都有利。有三种方法可以减少其他行为问题。首先，传统笼子的设计得到了改进，这对行为的某些方面产生了有利的影响，例如喂养。第二，已经测试了用于更大群鸟的笼子;例如，逃跑笼增加了行为自由，但也增加了攻击和同类相食等问题。第三，为传统的群体规模设计了新型笼架。许多行为问题-对于生产者，鸟类，或两者-发生在传统的笼子里，可以减少或防止通过增加笼子面积（包括宽度）和高度，并提供巢箱，灰尘浴，和鲈鱼。这些修改中的一些可以以对生产者来说可以忽略不计的成本来实施。如果鸡蛋的价格可以提高，或者如果关于蛋鸡饲养的立法发生变化，其他方法在商业上也是可行的。
Although they have many disadvantages for welfare, including for behavior, laying hen cages also have advantages. For example, aggression and cannibalism (or the need for beak trimming to prevent these) are usually less than in other systems, benefiting both the birds and the producer. There have been three approaches to reducing other behavioral problems. First, the design of conventional cages has been improved, which has had favorable effects on some aspects of behavior, such as feeding. Second, cages for larger groups of birds have been tested; for example, the getaway cage has increased behavioral freedom but has also increased problems such as aggression and cannibalism. Third, novel cages have been designed for conventional group sizes. Many of the behavioral problems-for producers, birds, or both-occurring in conventional cages can be reduced or prevented by increasing cage area (including width) and height and by providing a nest box, dust bath, and perch. Some of these modifications could be implemented at negligible cost to the producer. Others will be commercially viable if premium prices are available for eggs or if legislation on housing of laying hens changes.
