I have been incubating my eggs for 20 days now and i still don't see any development except for in one egg. They are due to hatch tomorrow. Even though I don't see any development, I also don't smell any wicked smells. Do you think it is worth it to crack an egg open. I literally have RIR eggs and only see development in one of them. the rest have what looks like a yolk just sitting there and kind of moves around as i turn the egg. Also, if i open an egg, and there is life, how do i close it back up. Finally, If only one of the eggs hatch won't they die of depression if they are all alone?
