Why can't we kill chickens at night?

There are rumors that you can't kill chickens for the following reasons:

Feudal society had low productivity, and people could barely maintain food and clothing. Coupled with some corvee taxes and wars, people easily died in this harsh environment, so people's fear of death at that time was far greater than that of modern times.

Because there was no electricity in feudal society, it was basically dark at night, and people couldn't see anything in the dark, and what people were most afraid of was the unknown (when they were alone in the house at night, they heard something in other rooms, and when they looked over, they found it was a cat; I was alone in the house at night, and I heard movement in other rooms, but I leaned down and found nothing. . . What is even more frightening is my own experience.

It is people's fear of death and unknown darkness that leads to many feudal superstitions. Because of the infinitely magnified unknown fear, I imagined many ghosts and monsters to kill myself, but in fact, without these things, I can't explain them, resulting in the imagination that others saved me, so I had God.

Killing chickens at night, after killing chickens, people have witnessed death, and they are somewhat empty in themselves, resulting in people's fear of death. Coupled with the unknown environment at night, they will be more afraid, and they will think that it is better to kill chickens during the day, at least without the unknown, only death. Over time, it will form a rule similar to not killing chickens at night.
