Sorry to hijack, but what else can you use if you don't have wax? The only wax I have is scented candles, don't think that would work! I also have a duck egg that has good veins on day 7, with a fairly large crack on the side. I noticed it before I put it in the bator, but I can't feel it with my nail, so I decided to set it anyway.
Same here. Its not a deep crack, but its there. I have scented candles too. Would a birthday candle work? It wouldn't be too hot to drip it on the egg?
are you afraid you will cook the egg? hardly,, woops, bad choice of words.. let's try , not likely..
I wonder how silicone caulk would work??
