Ok soo what should I be looking for. Well this is what I saw. Ok soo the dark speckled one forget seeing anything. sigh but the lighter ones I can see a dark section at the tip I assume thats the air sac? I saw the air sac yesterday but guess what I see today. A dark spot near the center. Not a tiny spot. soooo is that my yolk? Its like there is a darker spot in there too. I didn't see it yesterday but its clear as sin today. I should say we are 4 hours past our 4th full day. Soo 100 hours into the hatch lol. Yes I am wicked excited. No clue what I am seeing. I looked at the pics of candling but I see nothing like that. Granted this is a flash light, me and all brown eggs.
