Let’s Turn the Light on Egg Candling.
| Let’s talk about candling eggs so you know what to look for, how to candle , and why it is important.|
The chart shows the progress of the fertile egg.
Remember….Do not put your fresh fertile eggs in the refrigerator. It will cancel the fertility. And do not wash them as you may introduce bacteria into the embryo.
When you receive your eggs, let them rest for a few hours, then candle them. Record your findings on a chart. You can even label your eggs to coordinate with the chart but only use a pencil paint or marker may infiltrate the egg.
You may invest in a candler (they are for sale all over) or you may use a flashlight, candle, or even your cell phone. However you do it, just be
Candling is the name given to looking at the inside of a developing egg by shining a bright light through it.
This process is used by people who are incubating eggs for two reasons: to test whether an egg is good enough quality to go into the incubator and to see wether the embryo is developing as it should at different stages during incubation Candling gives clues as to whether you should expect problems during incubation and if the embryo has died, for example. In which case you would want to discard that particular egg.
What does a bad egg look like when candling?
The red blood ring – if you’re candling the eggs and detect a red ring of blood around the embryo, unfortunately the embryo has deceased and should be removed immediately from the incubator. Oozing substance – sometimes bad eggs will begin to ooze a honey/light brown colored substance.
How to candle.
Always wash you hands before candling to prevent bacteria getting onto the egg. The incubator is warm and humid and easily transmits bacteria. We certainly do not want that to happen. Candle on a soft surface. I like to use a towel or blanket so if the egg does drop it has less chance of breakage. You will need to turn the room light off, so it’s a good idea to have a flash light handy. Take eggs from the incubator one at a time, number then, or name them and keep your finding and name or number on a written chart. This will allow you to follow the progress of each egg in an organized fashion. (Just use a pencil to write on the egg to prevent ink from any marker absorbing into the egg.)Always candle the pointed end facing downward and be very gentle as to not jostle the egg.Keep the eggs outside the incubator for as long as it takes to candleIts a good idea to candle them before you put them into the incubator when you receive them. It is a good idea to discard any eggs you find infertile or a non live embryo or any egg that is cracked and may end up in seepage or explosion in your incubator. We do not want to take the chance of that happening or transmitting any contaminates.
I thought perhaps the following chart may be handy also.
