In fact, the reason why the black black chicken with green shell eggs does not lay green shell eggs is very simple: you can think from the perspective of biogenetics, it is possible that the paternal or maternal line of the chicken you buy provides her with the genetic factor of laying white eggs, and when the genetic factor of this white egg is dominant, she will lay white eggs; Green eggs are laid when they are naturally negative. Of course, it can also be understood that green is a kind of evolution, but if the black chicken is crossed with ordinary chickens, it will naturally degenerate to a certain extent, so it will degenerate into laying white eggs.
However, if it is mated with purebred black chickens, it is very likely that the offspring will still produce green-shell eggs. I think as long as it is a green shell egg, the nutritional value of the eggs laid by the black chicken, whether it is green or white, should remain the same, even if it changes, the nutrition is much better than that of ordinary chickens, after all, the black chicken is the nutrition that has been respected and loved by people since ancient times. . . My relatives and friends and I often eat Guishengyuan green shell black eggs, which is really good, and chickens are even better, and I love black chickens and green shell eggs as much as I do.
Friends may wish to try it too.

The reason why the green-shelled black chicken does not lay green-shell eggs is that after the black chicken is crossed with ordinary chickens, although it can sometimes produce chicken offspring with green eggshells, this trait does not always appear. At the same time, even if the black chicken can lay eggs with green shells, it will not necessarily be pure green. The color of the eggshell depends mainly on the hen's reproductive system, not on external factors.
Therefore, although green-shelled blackbirds may contain the genetic potential to produce green eggshells, they do not always lay green-shell eggs.

The biliverdin content is relatively high, so the color of the eggshell is green, or light green or dark green. The scientific name of the green shell egg is called "black egg", which is mainly produced by special breeds of chickens, the most common are the black chicken of the Three Gorges and the green black chicken of Hubei.
From the nutritional analysis, compared with ordinary eggs, the overall nutrition of green-shell eggs is higher, and the content of trace elements is also relatively high. The scientific name of the green shell egg is called "black egg", and it mainly has the black chicken of the Three Gorges and the green black chicken of Hubei.
Both kinds of chickens have a characteristic, that is, the feathers, skin, chicken, and even the internal organs and bones are black, so these two kinds of chickens are also called "black feather chickens".
Precautions for raising native chickens
1. Pay attention to density, the most important task of raising chickens is to pay attention to keeping warm, and in the summer, it is necessary to pay attention to heat dissipation, whether it is in the chicken coop or outdoors, it is very hot. And the chickens have grown a whole body of hair, which is even hotter in the summer.
When you return to the coop in the evening, be sure to pay attention to the density of the breeding. If a lot of chickens are crowded together, it will be even more uncomfortable, and the mental state will not be good. Relax the density appropriately to make them feel more comfortable.
2. Cooling, if the temperature is too high, the chicken will be in bad spirits, and the appetite is not good. Many people have passed a summer and the days have passed, and the chickens not only did not grow meat, but lost a lot of weight, which greatly affected the economic returns. Although it is not possible to install air conditioning in the chicken coop, there are some physical methods to cool them down.
For example, doors and windows must be opened so that ventilation can be carried out. On the roof can be sprayed with some water to cool down, water evaporation can take away part of the heat, ventilation is the key, if the humidity is large and not ventilated, it will become a steamer.

1. The green-shelled eggs laid by the native chickens are because the content of biliverdin and zinc chelate secreted by such native chickens is relatively high, resulting in the color of the eggshell being green, with light green and dark green, which is very special. Therefore, it is called a green-shelled egg or a green-skinned egg.
2. In terms of nutrition, compared with ordinary eggs, the overall nutrition of green shell eggs is a little higher, with high content of trace elements and low content of cholesterol and lipids. In terms of appearance, the shell of a green-shelled egg is slightly thicker, the egg white is more viscous, the yolk is yellow in color and reddish, and it is large and difficult to fall apart.

As we all know, black chicken is a kind of meat with high nutritional value, for the first recovery from serious illness or pregnant women, the nutritional value of black chicken is very high, mainly protein and some other nutritional elements, then,Is the black black chicken a green-shelled laying hen?Let's find out.

Therefore, black chicken has been considered a nourishing product since ancient times.
Black chicken is rich in melanin, protein, vitamins, 18 kinds of amino acids and a variety of trace elements, including niacin, vitamin E, phosphorus, iron, potassium, sodium content is higher than ordinary chicken, cholesterol and fat content is very low, black chicken serum total protein and globule protein content are significantly higher than ordinary chicken, black chicken contains amino acids higher than ordinary chicken, and the iron content is also much higher than ordinary chicken, is a tonic with high nutritional value.
1. Black-bone chicken is flat and sweet; It has the functions of nourishing yin and clearing heat, nourishing the liver and kidneys, strengthening the spleen and stopping diarrhea.

Black chicken: The plumage color is white, the weight of an adult rooster is about that, the weight of an adult hen is about that, and it can lay 80-100 eggs per year.
I. **
1. The green-shell laying hen, also known as the black-haired black-boned chicken of the Ming Dynasty, is the result of the natural hybridization of the ancient pure black-feathered black-haired chicken and pheasant, and the origin is Dongxiang, Jiangxi.
