在服务满9个月之后，这些母鸡通常会被执行安乐死，因为它们再也不能产下“最优质的鸡蛋”了，罗宾逊表示。
After nine months of service, they are typically euthanized because they can no longer lay 'optimal eggs,' Mr. Robinson said.
农业专家们也表示，这样罕见的情况实则是大自然的一种变异，如果母鸡在生蛋时受到惊吓，就可能产下异常的鸡蛋。
Experts say the rare phenomenon is just a quirk of nature and can occur if the chicken receives a shock during egg production.
人道“饲养的鸡染病的几率会减小，而有活动空间的鸡会更健康，则会产下更健康的鸡蛋。”
Humanely raised hens will be healthier as they will have room to move around in addition to being less susceptible to disease, and will therefore lay healthier eggs.
不过我们也可以看到，一些承诺只是一些人应该履行的职责，就像最常见的母鸡应该产鸡蛋一样。
But we may observe that. some of the promises are nothing but duties these people should fulfill, just like the most common eggs laid by the hen.
