I had stored some of our ee eggs for 5 days before putting in new homemade bator. I was trying to see into the oldest egg with my homemade candler and I dropped the first egg. It cracked / smashed one end so bad, I broke it into a dish to see if it was even fertile - And it was fertile. I could even see the heart beating. I took a video but, my camera won't let me transfer the thing. Here is a picture of how far along it was I guess I should look at the good side of this - I now know that storing eggs for 5 days in my basement and just rotating the eggs once a day works, homemade bator is working fine and so does our rooster ! Atleast, I still have 8 more ee eggs in bator. But How do you see in ee eggs????
