Ok, totally new here. I did spend a great deal of last night and this AM searching extensively for definitive answers before starting this thread. Even did a lot of googling, lol. So last night we candled eggs and most of them I either saw veins or not. I am on day 7/8 depending on which eggs because we got a few one day and then were handed some the next. I put in 15 mix breed egg layers and 3 silkies that a hen was sitting on. The following 2 eggs are the ones I am not sure about: This is one of the silkies...I am thinking a obvious clear, but why is there such a huge air pocket? Also the air bubble rolls around with it. Sounds like detached as described by others, but this was not a shipped egg... Is it normal for an egg to have this much air in it and feel hollow fertilized or not..? This one is 7 to 8 days old..great veining on the back side and then this side has a hazy dark mass. I candled from the end too, but the mass is better seen this way. I am not seeing clear defined edges like the pics I see of a blood ring...but the shadows remind me of streaking color..like when you drop food dye in water and it streaks out. Air sack is on the right side.. If it was further along I could understand darker mass but shouldn't I only be getting veins at this point? Is this the possible start to a blood ring?
