"Xinfeng's chicks are not enough. Do you have to go to Chang'an City for a walk?"

Chang'an City is the capital of the Han Empire, with a population of hundreds of thousands, which is many times more prosperous than Xinfeng, a small county town. Moreover, the nine cities in Chang'an gather all kinds of goods all over the world, so buying some chicks should not be a problem.

However, Zhang Ran felt hesitant, the price of chicks is a bit expensive now. In Xinfeng Market, the price of each chick is around fifteen cents. If it were Chang'an City, it would definitely be more than fifteen cents.

In this way, the cost is too high. You must know that the price of an adult hen is only 35 or 6 yuan now. Therefore, even if Zhang Ran raises the chicks, he will not make much money!

Other people's chickens are free-range, and at most they can only raise dozens of them, so it doesn't matter if they are expensive. However, my chickens have to be fed, and at least a few thousand at a time, which is incomparable!

What Zhang Ran wants to open a chicken farm, which is a large-scale breeding and must consider the cost. If the price of chicks has remained high and maintained at around ten cents, even if Zhang Ran opens the chicken farm, there will be no profit to say.

Therefore, buying chicks from the market and taking them back for breeding is definitely not a long-term solution, and it is really not a good idea.

Thinking of this, Zhang Ran couldn't help but think: "Maybe it's time to consider artificial hatching!"

The idea of ​​artificial hatching was found when Zhang Ran bought chicks at the market last time, but there were no tools at that time and there were no basic settings needed for manual hatching, so he was just thinking about it at that time.

Now that the new house is built, there will be a kang soon. Zhang Ran can consider trying it out.

In later generations, artificial incubation technology has become very mature. In the era of big data application and artificial intelligence, the survival rate of poultry eggs is very high, at least above 95%. In addition, artificial incubation can incubate thousands of chicks at one time.

Therefore, almost all chickens, ducks and geese in poultry farms in later generations were hatched through manual hatching.

However, there is no high-tech thing like artificial intelligence in this era. If Zhang Ran wants to use artificial incubation to hatch chicks by himself to reduce costs, he can only use the local method.

In his previous life, Zhang Ran grew up in the countryside and met the elderly in the village who used the method of hatching chickens by the fire kang to hatch chickens. However, the disadvantages of this method are very obvious. It can only hatch hundreds of eggs at a time, and it will not work any more. Moreover, the hatching process is very tiring, far from the technology of artificial intelligence management and hatching tens of thousands of chickens at a time, it is a backward technology that was eliminated very early.

However, even the technology that was eliminated by later technological transformation is definitely enough for Zhang Ran now.

After weighing the pros and cons, Zhang Ran made up his mind and said, "It just happened that he would have to put on a few kangs when he went back this time. After the kang was ready, you can try to incubate manually. If it doesn't work, it wouldn't be too late to go to Chang'an City to buy chicks!"

But for now, manual incubation is just Zhang Ran’s future idea for the time being, and even if he really develops artificial incubation technology after going back, it cannot solve the urgent problem.

Therefore, you still have to buy the chicks you should buy. Zhang Ran not only packed all the chicks in Xinfeng Poultry City in one breath, but also asked Sankui and Zhang Shan to buy a large amount of eggs in the Poultry City.

After the purchase was almost done, they drove a donkey cart with them, carrying a truck of stone, and a dozen chicken cages filled with chicks, and carrying a large basket of eggs, and returned to Zhangli.

...

The flue between the house and the kitchen was dug long before going to Xinfeng to buy stone. After Zhang Ran brought the stone back, he just needed to lay the stone slabs on it.

The process is very simple and there is no need to bother others. Zhang Ran, Sankui, Zhang Shan and seven or eight others were almost done after more than an hour of work.

The real difficulty is to repair the kang. Because Zhang Shan, Sankui and others have never seen the kang, and they don’t know how to repair it. Only Zhang Ran himself understands how to build the kang.

But if Zhang Ran did it himself, he wouldn't know when the four kangs would need to be repaired!

In order to repair the kang in the house as soon as possible, Zhang Ran first asked Sankui and a few people to dig some mud and clay by the river, and then asked Zhang Shan to boil some corn.

After the mud and clay were transported back, Zhang Ran asked everyone to mix the mud and clay together for stirring, and poured the boiled rice paste to increase its viscosity.

After these preparations were completed, Zhang Ran took the people to move the blue bricks into the house, and put some mud in wooden barrels and brought them into the house.

"I will demonstrate it to you first, and I will take a closer look. After I finish my studies, I will help me together!"

After turning around and instructing everyone, Zhang Ran picked up a blue brick and built the base of the first layer by himself. Then he used a wooden shovel to scoop out some mud from the wooden barrel and evenly applied it to the blue brick. After the entire blue brick was applied with a layer of thin and evenly mud, he picked up another blue brick to cover it on the mud and tapped it with the wooden shovel...

The second floor was laid, Zhang Ran stopped and turned to explain to everyone, "I saw that this is the same as building a house. Build a layer of blue bricks, apply a layer of mud, and build it up to three feet high... Pay attention to the distance between the brick walls. You must be able to cover a stone slab to be qualified. It cannot be too big or too small. After the stone slab is covered, you must touch the mud flat. After the mud is dried, you can use it to lay the mat!

"Did you remember it all?" Zhang Ran asked again with concern.

"Remember! Remember... what a big deal~"

"I thought it was so difficult, so it was so simple!"

"That's right, Brother Ran is so serious that I'm nervous... Is this necessary?"

After watching Zhang Ran's wall building process and listening to Zhang Ran's explanation, everyone made a "voice of the strong" and expressed disdain for Zhang Ran's small topic...

Seeing this scene, Zhang Ran almost turned black. He glared at Zhang Ying, who was the first to speak, and snorted coldly: "Since you have learned it, then start working!"

After saying that, Zhang Ranyou added: "I will watch you. If anyone has any trouble, don't think about eating meat at night!"

When everyone heard this, they exclaimed:

"Ah? No?"

"Brother Ran, you are too cruel!"

...

Facts have proved that Zhang Ran underestimated Zhang Ying and other peasant children. Although they had not received professional training, they did not stump them by building a few bricks and applying some mud...

The only disadvantage is that everyone's craftsmanship is very fashionable. The repaired kang has no connection with beauty when looking horizontally and vertically...

After the kang was repaired, Zhang Ran asked someone to burn the fire in the stove, and was about to try whether the kang was qualified, the connection between the gaps between the blue bricks, and whether there was a place where smoke was leaking...
