Reasons That Prevent Hatching Of Young Ornamental Birds From Eggs

To be a bird breeder in general or to be a breeder of ornamental birds in particular, it is very necessary that you face many, many problems in raising your birds, especially during the production period. Among these problems is the decline and death of young birds inside the egg, or their inability to exit it, and this is a very common problem for all breeders, regardless of their experience and experience in raising birds and caring for them. In this article, I will share with you most of what I have discovered about the causes of these problems, through my research, observations, and experiences on this subject, and with God’s blessings, we will begin with the details.

Too much humidity or too little humidity

Humidity is considered one of the important factors in the life of birds, especially during the production period. It is one of the important factors that plays a fundamental role in stimulating birds to produce. On average, the humidity during the production period reaches between 30 degrees Celsius and 60 degrees as a maximum. This value, which is limited to between 30 and 60, is where the body is. In a state of balance in which it does not feel either extreme cold or extreme heat, as is the case with birds, this is why humidity has an effect, either positive if it is at its normal levels on the bird’s egg shell in general, or negative: if it is very low, it causes drying of the internal and external egg shell and hinders breathing. The fetus is naturally inside the egg and suffocates as a result.

However, if the humidity is very high, it also has a negative effect, which is, firstly, preventing the stability of the natural temperature that is issued by the mother bird during incubation, which is 37.7 degrees Celsius, so it is difficult for the bird embryos to form inside the egg naturally, and the result is that their growth is either delayed or completely stopped. Secondly, during the hatching of the eggs, if The temperature was very high, the outer and inner shell of the egg was very sticky and at the same time rubbery, and thus it was difficult for the young to pierce it and get out of it by himself at the appropriate time or with the intervention of the female or the breeder.

Abnormal temperature

As I previously indicated in the first paragraph, as is the case with immoderate humidity, we find that temperature is one of the most important factors that affect the production of birds in a significant way, and even the life of birds in general. Glory be to God. Just as there is a biological clock inside the body, there is also what we call a biological thermometer. In other words, it controls the functions of the body as a whole in all creatures, as is the case in birds. The evidence for this is their behaviors such as the changing period, the rest period, the mating period, etc., from the periods of the life of birds in particular and the life of creatures in general, so that we do not delve too deeply into the natural temperature that they need. For all embryos in all animals, whether mammals or birds, to grow normally in the egg or in the uterus, they range approximately between 37.5 and 37.9 degrees Celsius, and on average it is approximately 37.7, which is the internal temperature that allows the embryos to grow well and naturally. This is of course in relation to body temperature, as for room temperature. It will be between 25 and 35 degrees Celsius, and this value is the correct value that the body of most bird species adopts in stimulating the hormones for mating. This temperature is mostly in the spring and may vary slightly from one country to another depending on several factors, including the nature of the climate, the location of the country, and also according to latitudes. And the length in which the region is located geographically.

Natural hours of light and darkness throughout the day

One of the most important factors in bird production, and even an important priority in production: natural balanced lighting. By natural, I mean its hours and not its physical form. It is one of the first motivational factors for the bird’s body in order to prepare for production and mating. As is the case with temperature and humidity, we find lighting, which is the main control of the body’s biological clock, which does not Anyone, no matter who, can deny that it has a very significant impact on the functioning of the rest of the organs of living bodies, and also on the way all of its systems function naturally. It is the software mechanism that controls wakefulness, sleep, and the body’s activity in general throughout the hours of the day, and this is according to a lot of research, experiments, and tests that It has been carried out by many international research centers and the examples are so many that there is no need to go into details. The important thing is that most birds, meaning 99 percent of them, do not prepare to produce until after the daylight hours become at least approximately equal to the nighttime hours. That is, after daylight hours reach 12 hours or more. Therefore, interference with the lighting system in an unnatural way negatively affects the nature of production and even the life of birds in general, which negatively affects the behavior of birds and the way they incubate eggs.

The eggs crack several days before the hatching date

One of the most important influences that prevent baby birds from emerging from their eggs, and even stops the baby from sleeping and dying most of the time. As for the causes of this problem, we find several reasons among them, among which I mention
Causes of cracked bird eggs. :
* Putting on an inappropriate ring, such as the rings that are installed on birds after they reach puberty, which are rings that are open and have sharp sides, also cause problems.
* The length of the nails of birds, especially the female, the longer the nails. The longer the more likely it is to get stuck to the threads of the nest while the female bird is perching on her eggs. After she gets up from the nest, her long nails get stuck in the threads, and she moves the eggs very violently, causing the eggs to collide with each other and crack.

* Providing cotton to the birds to collect the nest. It is one of the worst materials that can be given to birds for nesting because it is easy to stick to either the birds’ legs or the eggs, and this is enough reason to create problems.
* Moving the cage too frequently and also violently.* Moving the cage too often and violently.
* Place the cage in a shaky place, for example on moving surfaces, such as on top of the refrigerator.
* The nest is not suitable or it is moving and unstable, especially when birds move over it.
* Disturbing the female, monitoring her frequently, and forcing him to get up from the nest violently in order to watch for the eggs.

The female leaves her eggs for long and repeated periods

One of the reasons that prevent the embryos from growing inside the egg is that the female gets up from the nest too frequently, and the reason is that the temperature drops very sharply, especially after the first two days of the mother incubating the eggs.

The female’s lack of experience in incubating and turning eggs

Another reason for the death of the young is the virgin mother’s lack of experience in dealing with incubating eggs and her falling into the presence of what was previously mentioned in the previous paragraphs.

Finally and most importantly the fatal factor

There are many factors such as black spot and many hereditary diseases. As a simple explanation, it is a gene carried on the birds’ chromosomes. It is recessive, meaning it is not affected by it. Birds that carry it on their genes, but it appears when two birds who carry it mate and produce it. All the young that meet the genome die. The lethal factor is from the kidneys of the parents during their formation, and the effect is divided into two types: either the death of the young inside the egg when its growth stops at one of the stages or after it emerges from the egg, and the young often does not exceed three days.
For example: the black dot in Some of its cases, but not all of the black dots, were caused by the deadly agent, the mating of some varieties with certain characteristics to each other, such as the mating of a spotted Gloucester to another that has a tufted or a hat, and also the mating of some females bearing the mora to each other, when consanguineous marriage in some cases, etc.
