I have new hampshires that are 16 days in incubation. We candled them and several have large dark areas in them and on one side of the egg it looks empty. shouldn't the chick be taking up all of the egg space now with the exception of the air space at the bottom of the egg? Of course the eggs are brown so it is hard to see. My husband thinks I am being paranoid. I am just so worried. Would love to hear from the experts out there about what they have seen, I went on and saw a video of an egg at 16 days and you could see it moving all over the place, it was of course a white shell though, Thursday can not come fast enough for me now.
