Ok, I get it now, I can see the air sacs now! Thanks for the tip, all I had to do was tilt it a bit and there it was, plain as day. :) And here's a photo I took, too. I'm SO impressed with how much is actually detectable with just a flashlight! (But I'm not going to candle excessively - Promise!)
Another inquiry: I have an oblong, cream coloured egg that seems to be a pretty opaque shell like the Easter Egger blue ones I have; I can't make out any details with just the flashlight, but I see a darkish area that moves slightly, the yolk I presume. This mass looks darker than when I candled on Day 1. Is that any indicator of development? A darkening mass? I know I have to wait to know for sure with the dark eggs, but I was just wondering if I could take that as maybe a good sign, or if maybe it means the egg is a dud.
