Can shell-less eggs hatch chicks? It turns out that “cloud chicken farming” is really feasible

Those who have lived in the countryside have all seen the hatching of chicks. Rooster eggs are indispensable. However, with the advancement of science, the technology for hatching chicks is becoming more and more advanced. So, if there are eggs without eggshells, can chicks also be hatched?

This is completely possible, and it is a very mature technology . Let me tell you about it below.

01. Research on the culture of eggs without shells

The idea of ​​hatching chicks from shell-less eggs was proposed as early as the 1960s.

In 1971, late-stage egg shellless culture was completed;

In 1984, early egg shell culture was completed;

1988 was a peak year, when Perry MM cultivated the entire 22 days of egg development in one go. Every day was in hatching mode, and all were successful.

In fact, the research has ended here. What follows is just tinkering , such as how to improve efficiency and how to improve operations.

There are also practices that other countries like to imitate, for example, the Japanese did it, the Chinese did it, and so on.

Important documents: Perry MM. A complete culture system for the chick embryo. Nature ,331: 70-72. 1988.

The above technology completely solves the problem of culturing eggs without shells, but it is not recommended to try:

1. Most eggs sold in the market are unfertilized and cannot be incubated. Fertilized eggs are needed for incubation.

2. Key conditions for hatching eggs: temperature, humidity, air and pollution-free, which are not available in ordinary households

3. The eggshell removal technology is not strong enough.

02. How to hatch chicks from shell-less eggs?

There is a very popular video, which is a replication. Of course, simple replication is not enough, there must be something new. For example, I wrote an answer to "What do you think of "Japanese middle school students cracked eggs in a cup and hatched chicks in plastic wrap"? ". Here I will briefly explain it.

Their experimental design is as follows:

1. The real picture looks like this

2. The eggs inside are without shells. The next step is incubation.

The incubation time is 21 days, including 2 days of pre-incubation and 18 days of artificial culture. Oxygen supply begins on the 18th day.

These variables are mainly used to measure the effects of different cultures. For example, the effect of pre-incubation time

3. The influence of oxygen (the empty circle means no oxygen is added **, the solid circle means oxygen is added**). Pure oxygen is used for supplementation, which shows that the influence of oxygen is crucial after 18 days of incubation outside the shell.

4. The chicks they got in the end

OK, the article is translated. That is, this article repeats the history of previous incubations , proving that incubation without eggshells is entirely feasible . At the same time, they also used new materials and studied the effects of calcium addition and oxygen.

This is the end of the article. Hatching chicks from shell-less eggs is real and has been verified.
