I have three different sets of eggs in my bator. Some are on day 12, some on 11, some on 6. I candled them all just a while ago. They are hard to see....I have brown eggs. I do have a few questions about those on days 11 & 12. Should I see movement in them? Some are really dark and I can barely see any of the light through....is that normal? I have one egg that is almost transparent and I can see just a tiny glob on the bottom....not recognizable air sac....what should I do? Would pics help? Not sure my camera would cooperate but I can try if you think it would help....
