英语语法分析

Barn eggs, sometimes called Percher, are laid by hens that have the freedom to roam a henhouse.

谷仓蛋，有时被称为 Percher，是由在可以在鸡舍里自由漫步的母鸡下的蛋。

If an eggbox doesn't specifically say "Barn", "Percher" or "Free Range", the eggs that it contains are almost certainly battery produced.

如果一个鸡蛋盒没有特别标明“谷仓”、“高处栖息”或“散养”，那么里面的鸡蛋几乎肯定是批量生产的。
