My 1st time & I have 24 cayuga duck eggs on day 24. I just found that 3 of them have poked cracks & holes in their shells! Upon candling, I see about 80% are internally pipped, moving & chirping. I've taken them out of turner, but my question is how to lay them on the wire? I read that the lowest end of the air sac should be facing up, but that puts the cracks facing down. Which is more important to be facing up? Thanks!
