The weather in Shuangyashan City is 30 days.

My hometown is Shuangyashan City, Heilongjiang Province, and it is very, very cold in winter. As far as I can remember, the temperature in winter has been between MINUS 10 degrees and MINUS 30 degrees. Sometimes when the wind blows, there is still snow, plus the weather of MINUS 20 degrees, it is really cold. If you leave chickens and ducks outside, you will definitely freeze to death. I remember one winter when I was a child, I caught a sparrow and wanted to put it at home, but my room was carpeted and put it on my balcony, the kind with glass windows. I didn't think it would do any good at that time, but the poor sparrow froze to death the next morning, and his whole body was frozen stiff, like holding a stone in his hand. I feel really guilty. I deeply regret this stupid thing I did, and it also involved an innocent life. Sparrow, I'm sorry.

I'm sorry, the more you talk, the more beside the point. Let's not throw bricks. Let's begin to answer questions formally. I have a cousin who raises chickens. Chickens must be raised in the room in winter. If you leave them outside, they will soon freeze hard. The floor of the room should be covered with sawdust and the like. The floor should not be too thin, or it will freeze the chicken's feet. There is also a stove in the room to keep warm. I used to go in. In our country, most people have a house dedicated to chickens, ducks and pigs for winter, which is built at a distance from the house where people live.
