在玉米地养鸡是个好想法，但是，村民的田地都是一家挨着另一家，那些鸡肯定会到处乱跑，难道还要在自家地的周围扎上一圈铁丝网吗？

Raising chickens in cornfield is a good idea. But the villagers' fields are always one next to another, and the chicken will be definitely running around. Should everybody install a wire fence around their own land?

您提的问题很好，网围栏是为保证科学实验数据的准确性做的设计，而在具体实施时需要保证一定的玉米地面积，适合在合作社式的田地饲养，这样就不用担心鸡会乱跑。可以从林下养鸡得到证实。在活动范围比较大的情况下，围栏是不必要的。

The question you posed is very good. A chain-link fence is designed to ensure the accuracy of the scientific experiment data. But in the specific implementation we need to make sure there is a definite area of corn land suitable for cooperative style raising. Only then we can stop worrying about chickens running around. Raising chickens in forests confirmed this theory: when a fairly large roaming area is available, fences are not necessary.
