一只帕多瓦种的母鸡,在靠近帕尔玛城的一所农庄里出生长大,它有个毛病:生出的蛋的壳很容易碎。原因在于其他的母鸡都吃小石块和石灰微粒,所以它们生下的蛋壳都结实;而它只吃小麦、高粱和玉米粒,或者吃小虫子,它吃的虫子有玫瑰色的、黑色的和其他各种颜色的,它从来不吃小石子和石灰微粒,因为它消化不了。要是偶然吃下去一颗石子,那石子就整天待在它的胃里了,而且使它整夜合不上眼,所以,它生的蛋的壳很容易破碎。

The reason is that the other hens eat small stones and lime particles, so they give birth to eggshells are strong; and it only eat wheat, sorghum and corn kernels, or eat small bugs, it eats bugs have rosy, Black and other various colors, it never eat pebbles and lime particles, because it can not digest. If by chance a pebble is eaten, the pebble will remain in its stomach all day, and it will not fit in the night, so the shell of its raw egg is easily broken.
