Question. I have 6 eggs under my broody on day 12. Three of the eggs are pullet EE eggs. They were fairly good-sized so I used them. Well, they are sooo dark to candle right now and now I'm wondering if it could be that they were double yolkers and it is already so crowded in there. I can see the air sac and that's it. I saw veins in all three early on and now I only see dark. Do you think I have a chance at hatching them?
