Learning to candle.

[Uzuri]

Since my Javas have started up I'm starting to have hope again that I'll have extras within a couple months to sell XD

While I'll be selling to people at work all of whom are the type who like to learn and would not be upset to get the lecture on how blood spots, meat spots, and double yolks are all natural and won't hurt you, I'd still love to be able to run a quick candle on my extras and avoid having the subject even come up!

So I've had some difficulty finding images of candling OUTSIDE the context of doing so for hatching. I'm covered if I see a developing chick, I know to leave that one out

What I'd like to see are examples of blood and meat spots -- and also how to tell the yolk from the white!

I candled a dozen eggs this morning with a bright flashlight, and I was able to identify the air sac and tell a porous egg from one that was not. I'm fairly sure I had no (or very tiny) spots, and that fits with my experience with the eggs we've used from my hens so far -- I've only had a small number of very tiny meat spots. I couldn't identify the yolks, though, or at least wasn't convinced that I could. Maybe they were just a lot more subtle than I thought they were. Obviously the "pros" must be able to do this because they keep the doubles out of the supermarket cartons

So does anyone have any references for me? Tips?

It seems like it would be so difficult to candle at home for meat spots. Just seeing the yolk is tricky enough. I imagine that they have industrial strength candling lights in commercial operations.

Maube someone will come along who will have experience with this...

I believe commercial facilities use an Infra red laser detector to detect bad spots.
