Advice 1: How to check whether the egg embryo

There are several ways by which you can determine whether in the egg embryo. In the absence of a special device – candling, you can use traditional methods of finding out whether the fertilized egg.
How to check whether the egg embryo
To determine the quality of eggs and determine whether they are developing the embryo, there is a device candling. It is easy to use and its design is so simple that some craftsmen produce analogues of this device in his own home.

In this device there is a hole to which to attach eggs. Thus they are x-raying and found out whether there is a fetus. Before beginning the procedure it is recommended to thoroughly wash hands or wear thin rubber gloves. Note that lowering the temperature of eggs in the early stages of embryo development is fraught in his death. Therefore, in the room where an inspection is carried out by candling, it should be warm.

The whole procedure needs to occur quickly. Optimally, if you will attend an assistant who will serve eggs and put them after the x-raying in the incubator or nest. Checking eggs for the presence of the embryo should be carried out not earlier than 5-6 days after hatching. Until that time it will not give any results.

If the radiographic inspection showed that under the shell there is a clearly visible dark spot or area of yolk streaked with thin blood vessels, then the egg is life. The embryo is visible particularly well in case if it is located close to the shell. His lack of immersion in the yolk suggests that the development of the chicken leaves something to be desired.

Folk methods for determining oplodotvorennogo eggs

If no candling, and there is an old projector of slides, you can check with him. This egg is applied to the hole from which the light beam is supplied, and determines whether it is an embryo. Similar, but less comfortable way – using bright light bulbs (for example, 150 W). To avoid glare, you can do so: roll in a tube sheet of A4 paper and it one side to make the egg, which must be carefully adapted to the light source.

There is another interesting way to check whether there was fertilization. 3-4 days before the end of the hatching eggs need to atone. Each of them is alternately dipped into a bowl with a small amount of warm water and watch the behavior of the liquid. From the egg in which the fetus develops, the water going in circles, resembling those that come from the float when fishing. If fertilization did not occur or the embryo died, the water remains stationary.

Advice 2: How to check the eggs in the incubator

To make sure that the incubator fertile eggs and the embryo develops in them safely, you will need an ovoscope. If this device is not present, its counterpart can be done independently.
Check the eggs by candling before placing in the incubator
You will need
  • - candling or a homemade device for radiographic eggs
  • - tray to hold eggs
  • - rubber gloves
For incubation, it is desirable to lay eggs from their chickens, and not imported. Liluplanet often below 50% for the reason that during transportation from vibration and temperature changes the embryo dies. But it can happen and in that case, if the incubation process is somehow broken. So the farmers, there is a rule to check the eggs before laying on 6-7 and 11-13 day after.
How to test eggs in the incubator with the help of candling?

This procedure is carried out with extreme caution and only clean hands. You can wear thin rubber gloves. Take the egg you need two fingers to check and put back the pointy end down. The movement should be smooth and accurate. Each egg out of the incubator, it is necessary not only to validate with x-ray, but also inspect for sooting or cracks of the eggshell.
If candling is not available, you can make it analog: a simple design of a small cardboard box or a wooden drawer at the bottom which you want to install a light bulb small power (60-100 W). Directly above it is necessary to cut out a circle of such a size that the depression could fearlessly lay the egg. From the lamp to the lid of the box should be no more than 15 cm.
The candling or a homemade device may be best used in a darkened room. In this case, the result of scanning will be seen more clearly. During the inspection of the egg to gently and slowly rotate. The ambient temperature must be sufficient to prevent hypothermia of the embryo. To the verification procedure was more simple and less time consuming, next to the candling and it is recommended to install the storage tray of eggs and put them into it with the blunt end upwards. But we must also remember that, outside the incubator, the egg may be no more than two minutes.
How to determine whether an embryo is alive?

When candling eggs before placing in the incubator are often only visible the air chamber. The embryo and the embryo is visible as a faint shadow with indistinct borders. To determine whether the fertilized egg, is quite difficult. So farmers make culling on the basis of visual characteristics. For example, lay in the incubator only to large eggs with smooth clean shell. On a 6-7 day incubation can be distinguished in the sharpened end of the egg by a network of delicate blood vessels, and the embryo looks like a dark spot. If the vessels are not visible, it means the embryo is dead.
