Okay, so again, this is my first hatch. For candling my eggs, I am just taking them to a dark place and shining a very bright LED headlamp through their sides.
Upon first look at day 7, I was looking for veins, I thought that's what I should see. I probably checked about a dozen eggs and saw none. I was a little puzzled, as my temp and humidity have been pretty spot on, and I have been very attentive. This morning I read a little more about candling, and then took another look at a random sampling of eggs. I have 41 in the incubator. I can't see into many of the green and blue eggs, their shells just don't let any light pass through.
HOWEVER, I do see that in many, if not all, of the brown and light brown eggs I can see in, there is a dark thing, about the size of the yolk, that moves as I roll the egg. I was assuming this was just the yolk, but when I look at a fresh egg I don't see this dark thing. Is this what I am looking for? Is this a chick? What if I see no veins?
