5. candler the eggs:
Our factory's Aoxiang fully automatic incubation equipment is equipped with an egg illuminator, and users can also make their own egg illuminator. The egg is a translucent body. As long as the surrounding area is dark and the light is through, you can see the internal situation. The purpose of the egg is to check the hatching situation and pick up the eggs without sperm, dead sperm and some weak sperm. Tools for taking care of eggs: find a paper box (wooden box can also be used), put a 25W-40W light bulb inside, dig a 3.0cm hole in the paper box, and put the egg on the hole, so that you can see the inside from the side. Take the eggs three times:
On the fifth day after incubation for the first time, the eye spots can be seen. The blood vessels account for four fifths of the positive side of the egg, and the bright red color is normal egg. If the blood vessels account for less than four fifths of the positive side of the egg, the eye spots can not be seen, it is a weak sperm egg. If the blood vessels have blood circles, and the blood clots are dead sperm eggs. If the egg is shiny, only the shadow of the egg yolk can be seen, it is a spermless egg. Dead eggs, no eggs and some particularly weak eggs should be thrown away.
The second time the egg is photographed for 10 to 11 days, the blood vessels close at the small end of the egg to form a normal egg. If the blood vessels fail to close, it is a weak sperm egg. If the air chamber is vague, the embryo is in a black mass, and it is a stillborn egg.
For the third time, the egg is exposed to the light source for 18 days, and the small end of the egg is pointed at the light source, and the bright place can no longer be seen. Look at the big end close to the air chamber, and there is a red band with a width of about 1 cm, which is normal egg. If the band is not red, it is stillborn egg.
