Crack in egg|Please Help!

[Chickeroonie]

Hey guys!
Today I was candling my quail eggs and I realised that there was a very small crack in one of the eggs. The crack is not visible without candling it. I have seen many things that say to put candle wax on it but I’m not to sure if there is any point in doing that as the crack is so small. I don’t know if this is relevant but the eggs are only a couple days old. What should I do?

You definitely want to seal the crack. It will lose too much weight if not and it can allow bacteria to enter.
My advice is to use liquid bandage. Besides sealing, it has antiseptic properties.
I've successfully hatched 2 eggs using it. One egg was shattered with cracks over a third of it.

I would either seal it or discard it.
