On the European side, Marin's fleet continued westward after joining up with the battleship formation in the open sea. A few days later, we arrived on the coast of England. When they arrived at the Isle of Wight, Marlin's fleet stopped again. After all, the Isle of Wight was now a fief of Marin, and he decided to take the opportunity to inspect it.

Marin's fleet docked at the port of Coes at the mouth of the Medina River in the northern part of the Isle of Wight, and Coes was named after two sandbanks at the mouth of the Medina, much like two cows (Co), and then it became known as Coes.

It is located at the mouth of the Medina River, the larger freshwater river on the Isle of Wight, and the Solent Strait to the north faces Southampton Bay, an important freshwater port on the island. So, Cowes is a very good freshwater port.

Therefore, Marin had already invested in the construction of a castle in Cowes and built a number of long bridge piers to facilitate the docking of ships. In addition, a dock was built to facilitate the maintenance of the ships. After all, in the age of wooden boats, it was inevitable that the hull of the ship would be damaged by the maggots and the waves of the sea. So, the repair of the ship is important.

Moreover, in the future, Marin planned to build Cowes into an important military port. So, the dockyard of Cowes is not one, but three.

In order to ensure the safety of Cowes and avoid being attacked by the enemy fleet, Marin built a number of batteries on the shore of the Solent Strait, where Cowes leads to the sea, which are specially designed to attack enemy warships that dare to enter the strait.

You must know that the Solent Strait is only 3 lanes and 6 kilometers wide, and Marin has built several batteries on the shore, which is definitely enough to deal with enemy ships that dare to invade. After all, the guns of the batteries were generally of a larger caliber. Moreover, the recoil of the turret is transmitted to the ground by the base made of stone, so it will not be displaced like a naval gun, and it will not be misfired due to the shaking of the hull. In addition, the protection of the stone fortress is much higher than that of the wooden ship, so the battleship and the battery are definitely not opponents. As long as both sides of the Solent Strait are blocked with batteries, the port of Cowe is a very safe military port.

And the warships of the port of Cowes, as soon as they sailed from the Solent Strait, arrived in the middle of the English Channel, which was very advantageous for controlling the English Channel. In addition, the Portsmouth Military Port in the northeast of the Solent Strait was also the largest military port of the British Royal Navy, and it was also the place where the Royal Navy held a naval review ceremony to show off the naval power of the British Empire. Later, Wei Er was stimulated at the naval review ceremony here, and then went back to let the German Empire blow up warships......

Although the harbour on the other side of Portsmouth is better, it is backed by the mainland of England. Before England was under his control, Marin didn't want to expose too many of his secrets to the English. Therefore, it is the best choice to establish a military port on the island of Wight, which is completely its own. Anyway, it's the era of wooden sailboats, and the harbor doesn't need to be too big and too deep. A port like Port Cowes is competent enough.

Even, in order to maintain secrecy, the officials arranged by Marin on the Isle of Wight were all Frisians from East Frisians. These people speak the Frisian language and can communicate with the locals. Moreover, because they are die-hard Marin, they have nothing to do with England proper. With them, Marin is not worried about the infiltration of England on this side. And in a few years, the whole of England will fall into their own hands, and there will be no worries about the infiltration of England.

Arriving at Cowes Harbor, Marin found that Cowes Harbor was still under construction. Although a large amount of money was invested, it took a lot of time to build a port and a castle. Therefore, when Marin arrived at Cowes, Cowes had only repaired a number of longbridge docks. As for the dock and the castle, the castle was only half repaired, and only one of the three docks was repaired......

After all, it was his own territory, and at the warm invitation of his men, Marin traveled to Newport, the administrative center of the central Isle of Wight, to live at the famous Carisbrook Castle. The castle is famous, and later Charles I was imprisoned in this castle before he was guillotined......

Marin didn't have any taboos, after all, Charles I hadn't appeared in this world yet. Not to mention Charles I, Charles I's grandfather, James V, could not appear under Marin's intervention, so naturally there would be no Charles I. None of the unlucky Charles I had ever stayed there, and Carisbrook Castle naturally passed without bad luck.

Because the matter of going to the Americas to fight the war was fake, Marin was naturally not in a hurry to go to the Americas. So, on the Isle of Wight, Marin simply came for a vacation.

When he was not at work, Marin also took his guards around the White Lodge to enjoy the atmosphere of the island country of England, which is different from Germany.

That morning, Marin and his guards left Carisbrook Castle and went to a nearby village to play.

In the course of playing, Marin was surprised to find that a young English farmer named James, after picking up two duck eggs on the grass beach by the river, returned to the front and back of his house, lured the old hen in the chicken coop by the door with grain, and then quickly put the duck eggs in the chicken coop, and at the same time, took out two eggs from the chicken coop......

"Hey, what are you doing?" As Marin's bodyguard, Karn asked curiously. Karn also learned Frisian, so he was able to converse with English farmers.

James saw Marin, a large group of people in plate armor, who were obviously nobles. So, with a deep bow, he replied:

"Hello gentlemen, I just took the duck eggs to hatch the hens!" As soon as James finished speaking, the fed hen ran back to the coop and continued to hatch the eggs. However, the stupid old hen didn't realize that her eggs had been dropped......

Maybe people think it's incredible - there is such a big difference between an egg and a duck's egg, can a hen not notice it? Hey, I really didn't realize that hens are so stupid......

After listening to James's explanation, Karn was shocked - the hen was so stupid......

Then, he went on to ask:

"Why don't you give the eggs to the mother duck to hatch?"

"I don't know that female ducks don't like to hatch eggs. They usually run away after laying eggs, and basically ignore the eggs. Generally speaking, we leave the heavy task of duck egg hatching to the hens......"

Karn continued to be shocked......

Marin smiled, with a look of "I know everything". This kind of thing is that hens hatch duck eggs, Marlin has lived in the countryside in his previous life, so he has naturally seen a lot of them.

In fact, female ducks do not like to hatch eggs, which is also the result of long-term human selection. Because, it has been found that female ducks who do not like to hatch eggs grow fatter and stronger. After many generations of selection, the mother duck does not like to hatch eggs. And duck breeders, in order to get ducklings, can only take duck eggs to hatch stupid hens.

And the hen is really stupid, after the duck eggs hatch, the ducklings and the chicks are obviously very different, but the hens will still treat the ducklings as their own children, and when they find the bugs, they will warmly greet the ducklings to eat. One day, the duckling jumped into the river and swam merrily, and the hen was even more confused—how could this strange-looking child of mine swim?

However, this is all traditional farming. In fact, if you want to breed on a large scale, later generations will generally take fertilized duck eggs, and even goose eggs and eggs, to the kang room to hatch.

It should be pointed out that there are two types of eggs, one is a fertilized egg and the other is an unfertilized egg. In other words, eggs are actually eggs released by a hen. If it is not combined with the sperm of the rooster and becomes a fertilized egg, it will not be able to hatch chicks.

For example, when a woman has menstruation every month, she will also send out eggs, but they will be lost with blood and water. If fertilization is carried out before expulsion, pregnancy is carried and a child is born. However, the hen's eggs seem to be larger, and that is the egg......

Just like a woman's menstrual experience, the hen is not pecked by the rooster (the way chickens mate) and still lays eggs. However, women ovulate once a month, while hens ovulate every day. The eggs that are released are eaten by humans......

Identifying fertilized eggs from unfertilized eggs is simple – in a dark room, hold the eggs against the light and observe the eggs. If there is a shadow in the egg, it is a fertilized egg. If it's transparent inside, it's not.

However, there is another way to distinguish, in his previous life, when he was a child, Marin saw those who collected eggs, carrying two baskets, one basket with fertilized eggs, and the other with unfertilized ones. The way to distinguish is to first see if there is a big rooster in the chicken, there is a big rooster, and the hen will definitely not be spared, and most of the eggs of this hen are fertilized. If there is no big rooster, there is no neighbor (the neighbor's big rooster is nicknamed the old king next door, if the big rooster in the house is not careful, the big rooster next door will come to peck the cockscomb of the hen in the house...... Then, in order to maintain his own back palace, the big rooster in the family will have a fierce fight with the big rooster of the old king next door, which is the legendary cockfighting...... ）

Unfertilized eggs are generally sold to urban people to eat, while fertilized eggs are generally sold to kang houses to hatch into chicks......

"That's right, Kang room! Why did I forget about it! Marin patted his head and said.

In this era, there are probably already kang houses in Huaxia. The kang house is a kind of greenhouse for hatching chickens, ducklings, and geese, and the structure is very simple, it is a hut with a fire kang. However, the cabin is enclosed to maintain the temperature inside. The fertilized eggs, duck eggs and goose eggs are placed on the kang with a broken quilt or grass underneath (to prevent the temperature from being too high and steamed), and they continue to hatch.

The temperature of the kang room is definitely higher than the body temperature of the hen itself. Of course, the temperature should not be too high, otherwise the eggs will be baked. As long as the temperature is well controlled, incubation in the kang house is safer than that of hen incubation. Moreover, it can be incubated in large quantities.

The incubator of eggs is as high as dozens of days, and the hen can hatch up to two or three eggs at a time, which is very inefficient and very hard, squatting there all day long, which is not conducive to foraging and growth. Therefore, the incubation of later generations is generally done in the countryside to the kang house.

The chickens are a little better, after all, the hens are willing to hatch the eggs. And for ducks, the kang room is even more important. The mother ducks do not hatch eggs and lay eggs everywhere, and the duck herders often have to go to the river beach every day before finishing work.

Therefore, before the advent of the incubation technology in the kang house, the scale of duck breeding has not been able to rise. Because, duck eggs are not as good as female ducks are willing to hatch eggs. Handing over to the hen not only harms the hen's body (after all, it's not easy to squat there for a month), but also inefficient.

If you build a kang house to hatch, you can hatch hundreds of ducklings at a time. And even if there are hens that are willing to hatch eggs, the number of eggs hatched by the hens is very limited.

If it is replaced by a centralized incubation in a kang house, large-scale breeding of chickens, ducks and geese will no longer be a problem. And if the scale of chicken, duck and goose breeding increases, then the residents of Beihai will not lack chicken, duck and goose meat to eat, and there will be no shortage of eggs......

Therefore, the incubation technology of the kang house is a technology of great historical significance for the breeding of chickens, ducks and geese, especially the breeding of ducks. With this technology, the large-scale breeding of chickens, ducks and geese will no longer be a dream......

"It seems that we have to build a batch of kang houses!" Marin thought. Of course, this will have to wait until he returns from the Americas. As for the Isle of Wight, Marin does not plan to promote the technology for the time being. Good things, naturally, give priority to the local first. Then, other regions will be considered......
