Candling of eggs

Candling of eggs

It is a procedure where bright light is shone through and egg to view its interior in order to determine whether it is developing well. A developing egg in an incubator show signs of development like veining, the size of the air cell, or a growing embryo.

Procedure

  • Light source: The most crucial part of the candling process is the light source. A specialized egg candler is often preferred, but a strong flashlight or even your mobile phone can also do the trick.
  • Dark room: To properly look inside the interior of an egg, it’s best to carry out candling in a dark room. This enhances the visibility of what’s inside the egg.
  • Soft surface: While candling is done, you’ll want a soft surface like a towel or cushion where you can safely place the eggs from the incubator. This minimizes the risk of breaking or damaging the eggs.
  • Tweezers and sanitizer: Occasionally, you might notice foreign materials on the eggshell. Tweezers can help remove them, and sanitizer ensures everything remains hygienic.
  • Observation chart or notebook: Keeping track of what you see in each egg allows you to make informed decisions later. Note down observations like air cell size and any signs of development.
  • Gloves: Wearing gloves can minimize the transfer of oils or bacteria to the egg’s surface. It’s a simple but effective hygiene measure.
  • Timer or stopwatch: Keeping track of time ensures that eggs aren’t exposed to light for too long, which could affect the incubation process.
