Chapter Ninety-Five: Eggs

After sending away the big and small butchers, he turned back, and found Shi Wei squatting in front of the bamboo cage, looking at the little rooster in the cage: "Huh? Weier, didn't you go to build a chicken shed with your little sister? ”

Shi Wei stood up: "It's not fun to build a chicken shed to watch the uncle cut the belly of the chicken." ”

Okay, you are a tiger girl, you are powerful, Su You took her hand: "Yesterday, your eldest brother told me that the Heavenly Master wants you to learn medical skills, this is a good thing, you have to study hard, and protect the eldest family for a hundred years in the future." ”

"I'll cut a rabbit for you another day to get a first understanding of anatomy. It will be good for studying medicine in the future. Now, let's go see the chicken shed. ”

The chicken shed is made of bamboo poles, and one side is against the outer wall of the new house, and the top is covered with this year's newly harvested straw.

Inside the shed are square cages made of bamboo poles, each with a flap.

The outside of the cage is a half-cut bamboo tube, one for water and the other for feed, which will not be contaminated by feces.

Under each chicken coop, there is also a rough mat, made of bamboo strips and bamboo shoot shells, which is used to carry chicken manure.

The tools for the new home are very complete, the babies are also proficient, and the upper and lower rows of chicken cages are neat and tidy, and they have been pierced with a sense of beauty.

Su You shouted hello, these three rows of chicken coops have shown that the babies have made great progress in many aspects such as looking at the map, the use of rulers, the use of tools, and the division of labor.

Many small details are summed up in one place, and the standard and efficiency are formed.

Although it can't be compared with the craftsmanship of Dagong now, Su You believes that the progress of technology can always bring many benefits to Dasong after slowly accumulating step by step.

The next step is to put the chickens in the cage, add water, and add food.

The thick bamboo cages for chickens and ducks woven by the villagers were washed and dried, and Su You led the babies to process the various eggs received.

While the sun is still good, Su You almost habitually presses a bamboo tube on the egg, circles the gap between the two with his hand, and then puts the other head on his eyes to check the fertilization of the egg against the sun.

Well, the roosters and ducks in the village are very industrious, and the free-range guys, the welfare in this regard is still guaranteed.

After inspecting several eggs, I remembered that the thermometer did not come out, and artificial incubation seemed to be a bit difficult.

If you think of it, you can do it, this thing is actually not complicated, but it took a lot of effort to persuade Shi Wei to lend the clockwork in the brass frog and use it.

Seeing Shi Wei staring at the clockwork in his hand and the brass frog that had been broken into several pieces with tears in his eyes, Su You really felt that he had done a great sin.

I had to comfort Shi Wei and said: "Wei'er, with this thing, we can hatch chicks and ducklings by ourselves, and we don't have to trouble the mother chicken and the mother duck, I heard that the chicks and ducklings that have just come out of the shell will regard the person they see at first sight as their mother!" ”

Now Shi Wei was finally happy: "Really? Brother Xiaoyou, hurry up and get it, when the time comes, I will be my mother, and you will be my father! ”

Belch...... It's good if you're happy, Su You didn't dare to pick it up, so he directly found a thin copper strip, knocked it into a thin slice on the anvil, and asked Zhang Sheng to take a chopstick and press it on the table, and after pumping it a few times, the copper sheet became thick and even.

Use a ruler and a folding knife to cut the copper sheet into a neat copper skin, curl it up on the chopsticks, and then open it, just as there are a lot of fish bladders left from yesterday's banquet, boiling glue to glue the copper skin and the clockwork together, and wrap the fine silk thread around the outside to reinforce.

Glue the outermost edge of this thing to the inside of a bamboo tube, and the clockwork shaft in the center is just removed and replaced with a shaft with a pointer to glue it.

Then glue bamboo nets on both sides, leaving the eyes in the net a little larger to serve as a channel for air circulation.

The babies are also helping out, and it's a good time to spark interest in science.

Su You told everyone that this is called a temperature box, first sit at room temperature on the inside of the box to mark the position of the pointer, and then close the lid and let the children take turns to stick the inside of the armpit of the meat clip.

It soon became clear that the position of the pointer had shifted.

Su You explained to everyone that this is because the proportion of thermal expansion and contraction of copper and iron is different at different temperatures, and the body temperature is higher than the air temperature, which will cause the pointer to shift.

Then tell everyone that the child's body surface temperature is generally 36.5 degrees, and then brazenly use his own temperature as the standard of 36.5 degrees, and draw a scale.

The temperature box was placed in a bowl, and the plate was fastened to steam it, and soon the pointer changed dramatically.

The higher the air pressure, the better the fish opening, as a senior fishing friend, Su You knows the air pressure value of each season, and the air pressure in Meishan at this time is generally about 965 Pa.

Therefore, when converted to water temperature, it is actually 96 degrees Celsius to boil.

Two scales were obtained, and the difference in the middle was exactly about 60 degrees, so it was easy to mark the range of each degree.

This is also a very interesting question, how can you get a clear temperature indication when the thermometer is relatively small?

Xueba Su Xiaomei provides the perfect solution to expand the radius of the circle.

Su You gave a thumbs up in admiration, and then made a large disc that formed concentric circles with the temperature box, so that the separation distance between each degree on the large disc was magnified.

The next question is, what is the temperature today?

This is simple, because the scale has come out, and today the temperature is twelve degrees.

Next, everyone began to guess what the temperature of the hen should be when it hatched the eggs, and there were different opinions on this topic for a while, so Shi Wei came up with an idea to find a chicken that hatched the eggs and try it?!

So a group of babies came out of the house like bees, and Yachiko shouted: "It's almost time to eat, where are you going to run?!" Little oil, you're going to skin again?! ”

After looking for several in a row, and finally saw a satisfactory one at the fifth brother's house, Shi Wei clapped her hands: "This one is big!" This ass can sit still! ”

The old hen was not afraid of people, Su You lightly stuffed the thermometer under the hen's buttocks, and the old hen twisted her body and hatched the thermometer as a new egg.

A group of babies squatted down, holding their chin in their hands and looking around the old hens, as if they were also hatching eggs at first glance.

This posture made the fifth sister-in-law and the old hen very nervous: "Don't mess around, oil baby, you can't always let you send it to raise, sister-in-law is still counting on chicks......"

Ten minutes later, Su You took out the thermometer lightly, opened the box, and pointed a little more than thirty-eight degrees.

The normal body temperature of a hen is 40 to 42 degrees, and the conduction to the eggs is generally 38 to 39 degrees, which shows that the accuracy of this thermometer is still very high.

Su You laughed: "Go, go home!" ”

A group of babies said goodbye and left in a daze, making the fifth sister-in-law inexplicable: "This group of children! The oil baby is back, and it will not stop again! ”

There were still a lot of leftovers from the previous day, and Su You was ready to pick up a pot of smorgasbord that could be cooked together, and then deal with the cold vegetables and braised pork.

Zhang Sheng used the remaining bamboo and straw to surround a bamboo shed around the big stove where the banquet was held yesterday, removed the iron pot, covered it with a stone slab, sealed the mouth with wet mud, and left only a charcoal fire in the stove, and then spread straw on the stove to prepare it as an incubation room.

Su You came out to call someone to eat, and smiled at Zhang Sheng: "Yes, I don't need to remind you anymore, Brother Gou Yu knows what we're going to do next." ”

Zhang Sheng said with a smile: "After studying with the little master for so long, this little bit of eyes still has to rise." ”

After eating, everyone then picked up the lights and fought at night, others added straw, and Shi Wei and Su Xiaomei took a thermometer and put it on the straw to monitor the temperature.

The straw was spread to the thickness of three fingers, and the temperature was suitable.

Duck eggs are one degree cooler than eggs hatching temperature, so Su You divided the eggs into two layers, the next layer was placed with eggs, covered with straw, and another layer of duck eggs was placed on top.

The first batch was an experiment, so Su You only selected 30 pieces of each with basically the same development for incubation.

For the rest, leave enough for the babies to eat, then preserved eggs and salted eggs.

The next day, Su You began to lead the children to paste the wall with mud and straw as a thermal insulation measure.

Several windows were opened at the bottom of the room, and the inside and outside were covered with thin silk brushed with tung oil, barely solving the problem of light.

The reason why it is open at the bottom is because the cold air will only stay at the bottom, while the hot air can continue to hold on to the top.

However, this is another problem of rat prevention, so Su You had to go to the village to borrow two old cats to guard.

But Sujia Village in Longli is a sensation again, and the oil baby is really starting to mess around again! He's going to hatch eggs this time!

A few days later, Shi Fu took Shi Tong and Shi Dalai to repair the small kiln, and when he saw Su You, he gave his hand seriously: "In ancient times, there was a hen Si Chen, and now there is Mingrun hatching eggs, which is amazing!" ”
