In fact, this is a difficult question: because we don't understand what hens think, we can only speculate on its psychological state. It is generally believed that this is a kind of showing off, because chickens are animals with strong sense of living, and eggs can be said to be a big result of chickens as a group reproduction, or they are seeking comfort from the rooster. First of all, the rooster will come over to find some foods on the ground to give a reward to the mother, and the hens will get the only pet, and they will also be happy to eat. However, some people later thought that it was not that simple. The behavior of animals was actually quite complicated. Each animal had their thinking mode.Scientists generally believe that chickens can make 24 different sounds, and each meaning is very complicated. The tweets after the eggs are just one of them. Therefore, these explanations are just speculation, unless we study the ancestors of modern chicken, we may never know the meaning of these calls.
In the end, there is a problem, whether there is chickens or eggs first, welcome everyone to discuss the comment area
实际上这是一个不好解答的问题：因为我们并不了解母鸡是怎么想的，只能推测其心理状态。一般认为这是一种炫耀行为，因为鸡是群居意识很强的动物，而下蛋可以说是鸡为群体繁衍奉献的一大成绩，又或者是在向公鸡寻求安慰。首先公鸡会跑过来从地上找些食物对母给予奖赏，母鸡也就获得了独宠，也会开心取食。不过后来有人研究后认为不是这么简单，动物的行为其实是相当复杂，每一种动物都有它们的思维模式。科学家们普遍认为鸡可以发出24种不同声音，而且每种的含义都非常复杂，下蛋后的鸣叫只是其中一种。所以这些解释也只是人们的推测，除非我们深入研究现代鸡的祖先，否则我们可能永远不会知道这些叫声的含义。
最后有个问题，是先有鸡还是先有蛋，欢迎大家评论区讨论
