HI. I am currently incubating my first batch that is due to hatch the 21st. The eggs are in a super cool Brinsea Octagon borrowed from a friend, which I have learned is pretty nice as I don't have to do anything. But tonight I noticed that one of the eggs has the start of a small hole at the top. Is is normal for them to try to come out early? Also, I know the big end goes up,but sometimes it can be hard to tell which end is the big end. If I have some of them screwed up, will the chicks drown? Is it better to leave them on their sides for the incubation process?
