how in the world do you candle ( candling )an easter egg...

[wildrooster1]

my ameracauna hen has been laying beautiful dark green eggs, but for the life of me can't figure out how to candle them to tell if they are fertile... any suggestions would be a blessing, thanks in advanced..

you cant really tell if they're fertile by candling them. You can tell if there is a developing embryo by candling them. crack the egg open to see if it is fertile. To see if there is a developing embryo, candle them with a maglite. I found maglites to be the best. They are really strong to penetrate the color of the egg.

Fertility is checked first by breaking one open and looking for the bullseye in the egg.
Once you are incubating, I never bother candling an EE egg until at least 2 weeks. The shell is too opaque to see much before then and the only thing you really do see is the light portion of the air sac vs the dark chick. If you have a clear, it is very obvious at that point in comparison.
