Yeah, I understand that.... My point is that there is no need for it.... Why do it??? Besides, have you ever heard that saying "dont count your chickens before they hatch"???LOL.... You cant tell by candling if an egg is going to hatch or not.....
Saying that I guess it all depends on the curiousity of the breeder. Personally I like to candle them so I can separate the fertiles from the infertiles. If an infertile egg is put into a container with good eggs and that infertile egg goes bad, it could mean danger for the good eggs. When an egg starts to go bad, it gives off a harmful gas which could harm other eggs. If one of those eggs goes unnoticed, it could be disaster for all the other eggs. Everyone has different views on this. I like to candle them, you would rather let it be a surprise.
Yeah, you might be right but why bother taking a chance??? No one is immune to a laps in hand-eye coordination...
To me it is just risking eggs for a useless act....
