This Video is About Eggs Candling Procedure by Dr. ARSHAD. Eggs are Candeled to Properly Determine the Condition of the Yolk, White and Air Cell. Candling defects Bloody Whites, Bloody Spots, Or Meat Spots And enables Observation of Germ Development. Candling is Done in a Darker Room With the Egg Held before a Light. The Light Penetrates the Egg And makes it possible to observe the inside of the Egg. The Candler Should be set On aBox or Table at a Convenient Height So the Light will not Shine Directly into the Eyes of Operator. The Egg is Held in a Slanting Position With Large End against the Hole In the Candler. The Egg is Grasped by the Small End and while Held between the Thumb and Tips Of the First Two Fingers, is turned Quickly to the Left or Right. This Moves the Content of the Egg and Throws the Yolk Nearer the Shell. In Fresh Egg The Air Space is Visible and Moves Freely. The White is Thin and Clear. Most Newly Laid Eggs are Good Quality. The Only Eggs to be Removed Are those with Bloody Whites, Blood or Meat Spots and Cracked Shells. Incubated Eggs are Candled to Determine Whether They are Fertile Or Not, and if Fertile, to Check the Growth and Development of the Embryo. A small Reddish area with Blood vessels Extending away from it will be visible In Fertile Eggs. This is the Embryo Floating around inside the Egg, Looking like a Huge Red Spider. If the Embryo dies, the Blood Draws away from the Embryo and farms what is called the Blood Ring. All Clear Eggs, and Eggs showing Blood Ring or Streaks should be removed from the Incubator.
