Last night I decided to candle my shipped eggs (EEs) that were around 4 hours into day 6. I haven't had high hopes on them due to how they arrived. Most of them look just like they did when they were put in 6 days ago. There are 2 that I can't see into at all because of the olive colored shell. But, there are 2 that look different. The top half of the egg was a dark mass. If I turned the egg upside down to candle it, the whole thing was dark because the light could not shine through the mass. From the pictures that I've seen, this isn't normal for day 6. What do you guys think?
