Ovoscope
In late spring and early summer, farmers begin to grow a new number of birds. Someone entrusts the work to brood hens, and some resort to the help of incubators . And if in the first case you can do without translucence, then in the second ovoscope is needed.

How to make an ovoscope? To make it yourself, you can use the items that are in every house: from a tin can to a flashlight. There are many options for homemade devices, we will consider how to build the best and easiest to produce ovoscope do it yourself.
Prepare in advance:
- A cardboard box for pringles or something similar of the same diameter.
- Energy-saving lamp (voltage no more 20W). It is forbidden to use incandescent lamps, they get very hot during operation, thereby harming the egg and melting the body of the structure.
- Cord cut with switch and plug.
- Cartridge.
- Plastic jar of sour cream. Important!The diameter of this can should be several millimeters smaller than the cardboard packaging for chips so that the first fits comfortably into the second.
Instructions for the manufacture of the device:
- Take a plastic jar and cut off the top of the millimeter by 2 around the perimeter.
- Turn the jar upside down, attach the cartridge, circle it with a marker and make a hole using scissors.
- Insert the bottom of the cartridge into the cut out hole .
- Take the can from the chips in the lower part (not at the bottom, but a few millimeters higher ) with an awl, pierce another small hole for the wire with your skillful hands.
- Insert the wire through the hole made with the awl with the cleaned end, into the jar so that it goes through the whole package of chips, then goes into the sour cream jar and connects with the contacts on the cartridge.
- Screw the cartridge.
- After screwing in the light bulb, insert the sour cream jar into the chip box so that the light bulb looks up.
- When Using foil or other improvised materials, make the opacity of the chips cover.
- Take a marker, draw on the lid there is an oval shaped like an egg, but slightly smaller in size. Cut the appropriate hole.
- Put the lid on the box of chips.
The homemade ovoscope is ready, you can plug the cord into a power outlet and check whether the device determines the condition of the egg correctly. How to use an ovoscope?
To do this, place it over the hole in the lid and examine the embryo for several minutes on all sides. An ovoscope for checking eggs works fine.
Cost of a factory ovoscope
Of course, compared to factory ones, such as an ovoscope, the device made has simpler characteristics and check with it, at the same time, you can only have one egg, not a dozen, but a homemade device performs its main function 100%. In addition, the cost of our device is only a few hundred rubles for checking the incubation of domestic chicken eggs, while the factory one in the store costs about 2000 – 3000 rubles, but the principle of operation and appearance do not affect the final result.
If you do not want to do The device is yours to check the embryo during incubation, but you do not need an ovoscope for 10 or more eggs, pay attention to the model ОВ1-60-Д (Belarusian manufacturer). This device costs several times less than the previous one, it has only one technical mode of operation and you can check no more than one egg at a time on it. But the price does not affect the quality of the test at all.
Buying a desktop ovoscope or making it at home is half the battle, it is important to understand the principle of its operation and know the instructions for use and on which day to inspect embryo.
How to use the device
It’s not advisable to disturb the fertilized embryos daily with translucency, this can destroy the embryo. The best option is to inspect the eggs for clearance 2 times a week, in the early stages of incubation, you can less often than one day. Before the procedure, it is necessary to wash your hands and put on sterile latex gloves so as not to put destructive bacteria and microorganisms on the egg and not harm the incubations .
How to check the egg with an ovoscope
To view, place the egg over the hole, then turn on the lamp and carefully inspect the embryo from all sides (to shine for no more than five minutes, the best option is 1-3) .Place only the best eggs in the incubator, ovoscopy of which showed that they have:
- The structure of the shell is uniform .
- The borders of the yolk are blurred, and it is located in the middle or closer to the dull part of the egg.
- The boundaries of the air cushion are clear, it is very small, its location is also on the obtuse side.
- During rotation, the movement of the yolk mass noticeably slows down.
- There are no inside extraneous inclusions.
It is pointless to use a household ovoscope to check freshly laid eggs. The first procedure should be carried out only on the 5th day, when this period passes, an air cushion will already be formed, the yolk will thicken a little and it will be clear whether this egg is suitable for incubation, that is, hatching or not.
