Vaccinating chickens in the summer was hard work, and after the 2,000 chicks were vaccinated, the four of them were tired and sweaty.

After vaccination, I am more worried about the stress response in the large group, which will affect the feeding intake of the large group, and even cause sporadic casualties in serious cases.

Free-range greenhouses, strong chicks in large groups will bully weak chicks, casualties are inevitable, under normal circumstances, if the survival rate of chicks can be controlled at more than 95%, it is considered very successful.

In the two weeks after the chicks were free-range in the greenhouse, the casualty rate of the chicks was the highest. Therefore, the 50 chickens donated in the chicken farm are actually to supplement the casualties.

After the vaccination, it was already half past eleven at night. Now Wang Fumin's efficiency in doing this work is not very high, and after raising two or three batches of chickens, four people will vaccinate 2,000 chickens, and it will be finished in about 40 minutes.

After that, Wang Fumin, Ma Zhentang and Wang Shaodong went to the quicksand river in the north of the village to wash it off before going home to rest.

The weather forecast said that there would be heavy rainstorms in the next two days, and Wang Fumin and the three of them did not dare to stay in the river for a long time.

That night, Wang Fumin stayed in the chicken coop to sleep, and when he was in charge of watching the **** boy, he was afraid that the weather would suddenly become cold. If the temperature drops by four or five degrees all of a sudden, the chicks will be crowded together, and then the chicks squeezed below will die of suffocation due to lack of oxygen. Especially on rainy days in summer, the air humidity is high, and the chickens are wet after being crowded together, even if they do not die of hypoxia, they may cause dysentery and other diseases, and the consequences are also very serious.

In summer, there is a lot of rain, so it is necessary to prevent gastrointestinal and respiratory diseases.

After getting up the next day, Wang Shaodong saw that the weather was gloomy and the air was very hot, so he knew that the rainstorm was not far away.

This heavy rain has been brewing for a long time, and the memories of his past life suddenly appear in front of his eyes again.

About a few days after the college entrance examination results came out to fill in the volunteers, a heavy rain that lasted for three days baptized the entire small mountain village.

After thinking of the heavy rain, Wang Shaodong immediately became nervous.

If it rains continuously, the windows of the chicken farm cannot be opened, which will definitely lead to excessive humidity in the house, which is easy to cause a series of chicken diseases.

Thinking of this, Wang Shaodong immediately ran to the chicken coop and said to Wang Fumin: "Dad, it's going to rain, and the weather forecast says it's cloudy." ”

In the past two days, because a family of three has taken turns on duty in the chicken coop to take care of the chicks, where is the time to see what weather forecast. But how do you improve the credibility of what you say? I can only lie and say that I look at the weather forecast.

When Wang Fumin heard this, he shook his head and sighed and said, "Hey, the little chicks are afraid of the weather changes for the first two weeks, so we have to keep an eye on the chicken coop more in the past two days." ”

Wang Fumin obviously didn't know the consequences of this cloudy day, Wang Shaodong took a turn in the chicken coop and observed.

The chicken coop, which is more than 100 meters long, is surrounded by a closed chicken coop with white thick plastic cloth in the middle position, and the chicks are now raised in this area of about dozens of square meters. The enclosed coop is covered with wheat straw and wood chips, and underneath is a layer of fresh dry soil. As the chickens grow day by day, the enclosed chicken coop will gradually expand, and finally the entire 2,000 chickens will be completely dispersed and raised in the whole greenhouse.

After turning around, Wang Shaodong found that when the greenhouse was designed, the ventilation mainly relied on opening the windows, and he did not consider the fact that the windows could not be opened due to heavy rain in summer.

Seeing this, Wang Shaodong became a little anxious.

Wang Shaodong remembered that the heavy rain was so heavy that year, the flood in the river came fiercely, and the Shizi River on the other side of Qingquanling actually washed down more than 30 catties of large grass carp.

Such a heavy precipitation, such a long period of cloudy days, and the chicks in their own chicken farm are so big, if you don't take some measures, it will not work.

Suddenly, Wang Shaodong looked up and saw that there seemed to be a round hole in the roof of the greenhouse, and hurriedly asked, "Dad, what is that." ”

Wang Fumin glanced up and said to Wang Shaodong: "That's the chimney hole used to burn the hearth when it's cold. ”

Although the chimney outlet is now covered with plastic sheeting, you can still see that the place is different from other places. Because it's summer, the chicks don't need to use the stove to heat up, so the chimney has long been demolished.

Wang Shaodong patted his thigh, nodded and said, "There is a way." ”

Then, Wang Shaodong ran back to the house, asked his mother for 200 yuan, and didn't say what to do, got on the motorcycle and left.

Wang Shaodong knew that it was just morning, and the heavy rain would not fall yet.

The rain began at noon today and continued for three days.

After riding a motorcycle, Wang Shaodong came directly to a street of hardware stores in the county, inquired, and found a special shop that sells ventilation and exhaust fans for breeding greenhouses, and then spent 190 yuan to buy two.

Now the chicken coop for raising chicks is still relatively small, and an exhaust fan is enough, and Wang Shaodong buys two for spare. In case the exhaust fan is broken on a rainy day and you can't fix it yourself, you will be in trouble.

After buying the exhaust fan, Wang Shaodong didn't dare to delay his efforts, so he returned directly to Taohualing Village.

After returning home, Wang Shaodong hurriedly unpacked the package, took the exhaust fan and entered the chicken greenhouse.

Wang Fumin and Zhao Shiling are spreading plastic sheeting under the chicken coop, and then sprinkling chick feed on the plastic sheeting for the chicks to eat.

The chicks are too small to be fed in the feed trough, so they can only use this more troublesome method.

"Dad, you're here to help. ”

Wang Shaodong grabbed the exhaust fan with one hand and the pliers with the other, and said to Wang Fumin.

Wang Fumin had never seen an exhaust fan, and it looked a bit like a fan on the outside, so he asked, "What is this?"

"Exhaust fan, wait for more rainy days, the air in the chicken coop is too humid to be discharged. ”

Hearing his son do this, Wang Fumin felt that his son must have seen it from the book again, and he didn't ask in detail, nodded, and then asked, "Where to stay?"

Wang Shaodong raised his head and pointed to the chimney mouth and said, "That's it." ”

The size of the exhaust fan is similar to that of the chimney, and the exhaust fan bought by Wang Shaodong has a waterproof function and is specially placed on the roof.

Seeing that the things were bought, and those who didn't need them were needed, Wang Fumin could only rely on his son.

Wang Shaodong climbed onto the roof of the greenhouse, and then directed his father Wang Fumin to hand things up and down, and worked hard for a while before installing the exhaust fan.

Zhao Shiling was puzzled, shook her head and asked, "It's so troublesome to raise chickens?"

Wang Shaodong said in his heart, this is not called trouble, this is called experience.

I came here with my father's many years of experience in raising chickens in my previous life, so I naturally knew more than my parents. At the same time, Wang Fumin and his family also found that their son raised chickens, but he was really not ambiguous at all, and even understood much more than the two of them.
