I've been candling for awhile now, but this is my first time incubating my own eggs. I do not have an auto-turner, so I've placed the eggs in an egg carton (big end up) and have been tilting the whole incubator using a block on each side. Today is day 7 and although I do see eyes in some of them, a lot of them seem to be "hiding". The veining comes from the very top of the egg, and I'm wondering if I can't see them because they have latched themselves right onto the air cell where I can't see well? Has this ever happened to anyone? The ones I do see are right at the edge of the air cell and close enough to the shell for me to get a good look.
