我们吃的很多鸡蛋大部分并不含有胚胎，即使自由圈养的鸡蛋也有可能并没有发展到我们称之为吃小鸡的地步。

After the egg is laid the embryo stays in a kind of suspended animation until the hen sits on it to incubate it. If the egg is not incubated within a few weeks the embryo will die. This is how things work with a fertilized egg, the kind one might get directly from a small farmer. The second scenario involves the eggs we buy at the local supermarket, which come from what are called "egg factories." The egg factories rely on a peculiarity of chickens: they lay eggs whether or not they're fertilized. The egg factories do not have roosters in residence to fertilize the eggs, and these eggs will not develop into baby chicks. So, the eggs that most of us eat do not have embryos, and even the egg cells in the "free-range" eggs probably have not developed enough to be at the stage where one would be eating a baby chick. So, Mr. Hirose wins the bet, and maybe he'll want to buy an omelet with his winnings.
在鸡蛋被排出之后，胚胎保持为临时的生命状态直到母鸡坐在这些鸡蛋上面孵化它。如果鸡蛋在几周之内没有没孵化，这一胚胎便会死亡。这便是直接从一个农民手中得到的受精鸡蛋的成长过程。 第二种情况包括我们在当地超市中购买的鸡蛋，这些鸡蛋来自与我们称之的鸡蛋工厂。鸡蛋工厂依赖的是特殊的鸡：他们不管受不受精都会下蛋。鸡蛋工厂为了避免鸡蛋受精并没有公鸡，这些鸡蛋不会发展为小鸡。 因此，我们吃的很多鸡蛋大部分并不含有胚胎，即使自由圈养的鸡蛋也有可能并没有发展到我们称之为吃小鸡的地步。 因此，Hirose先生赢了，也许他会希望用赢的钱买个鸡蛋饼。
