I don't do that! I know others do...Sorry if I'm being a pain, but I have another pre-lockdown question. I have seen where most of you trace the air cell before lock down and find the lowest spot since this is where the chick will most likely pip. When you trace the air cell, should the egg be vertical or horizontal? This may be a silly question, but I just want to make sure I do it correctly. I'm thinking probably with the egg vertical with big end up...is this right??
