Day 11 and it looks like 2 of my dozen have a blood ring but I am going to wait a few more days and see if there are any advancements. As for the other eggs, they're very active XD I have a special marking on one because it has some cracking over the air cell that you can only see when you candle the air cell. Dunno if that is going to cause a problem or not. The aircell is growing well.
