I candled today (day 10) and saw movement in almost all of them (19 eggs total - 7 pure ameraucana - 11 easter eggers & 1 golden cuckoo marans). It was very exciting. I have a good candler this time and saw much more detail than I did the last time we hatched eggs from our broody (also the first time I hatched any eggs).
There were some eggs that were pretty dark - I didn't see movement, but did see plenty of veins and they had a large amount of dark area. I have one egg that is pretty iffy - I know it started to develop, there are a few veins, but not like the rest and there is less dark area than the rest. It is a huge Cuckoo Marans egg (my only marans egg). I think it may have died earlier, but since I don't see a bloodring I will wait and candle it again in a few days.
I had started with 22 eggs - 2 were clear and I took one out at day 7 because it had a definite blood ring - broke it open and didn't see anything inside but the blood ring on the shell.
