I keep reading that the air sac should be at the fat end of the egg. My eggs are at either 16 or 18 days depending. Long story. THe air sacs are all at the pointed ends of my eggs. Most of them appear to be heading to the air sac (head toward it) Everything I have read says they need to turn. But will the air sac move too? If not should I just leave it alone. I cut an egg carton and stood them on pointed end. SOme are not really that pointed. I was going to check to night to see if they turned. I got concerned that I was making a mistake as If the chicken turns and the air sac doesn't, then wouldn't they pip into the wrong spot and just die? I am so worried. this is my first batch and there are two from my girl that got killed. I REALLY don't want to lose them now. Please help.
