I do have another question about candling. I have at least two eggs that are very dark, like they look more like pictures I see of like day 13 or so. I don't see any movement, but just very dark, on one, I can also see some veining.
I guess I didn't actually ask a question.... are these bad eggs, good eggs, either?
When I am incubating dark eggs, I go by the air sac, because they sure can go dark fast. If you see veining, great! There will be a time that you may not even see that. That's when you have to go by the air sac. Is there one? Is it a nice bright air sac? Some are dull, and it's just impossible to tell, but some are waay dull, you would know the difference in how it looks if you have been watching. Those dark eggs are hard all right.
