It's your dead chicks take the longest hatchin'.

这是你死去小鸡孵化时间最长。

The most dangerous time is the first few weeks when they're smallest.

最危险时间便是孵化后不久，当它们最弱小时候。

And the shorter a bird's incubation time is, the less vulnerable its young will be to predators.

一只鸟孵化时间越短，它幼鸟越不容易受到捕食者伤害。

While they're inside, the embryos take in a lot of nutrients from the mother and are developed enough that they hatch in less than 2 weeks.

当它们里面时，胚胎从母亲那里吸收了大量营养，并且发育得足够好，不到 2 周时间内孵化。

Then, terrified, they rush back to their mother and climb on her back to wait for what is now to them the tedious business of the rest of the hatching.

然后，它们惊恐地冲回它们母亲身边， 爬到她背上， 等待孵化剩下时间对它们来说是乏味事情。

This was effected by Mr. Eyton, who raised two hybrids from the same parents, but from different hatches; and from these two birds he raised no less than eight hybrids (grandchildren of the pure geese) from one nest.

这是由埃顿先生造成， 他从同一亲本中培育出两只杂交种， 但孵化时间不同。从这两只鸟中， 他从一个巢中育出了不少于八只杂种（纯鹅孙子）。
