I got a dozen eggs in the mail 23 days ago. They had floating air sacs, but thought it would be fine. It is now day 23, no signs of life. 11/12 eggs were empty and one chick-in-egg still remains. No peeping, kicking, or any signs of life, but also no smell or veining on egg. What do you think I should do? The temperature has been fluctuating quite a bit...could that have killed it? Do I wait, Take a peek, or just plain give it up?
