Well I did it...I cracked open the egg. Found to me, what looks like, an undeveloped little blue chick. All sorts of organs and intestines outside of the body, which leaves me to believe it never finished developing. Did some googling looked like this chick on Day 19. So maybe as I broke open the shell the yolk sac broke leaving all the organs out and thats what I saw. Either way they were not inside the body yet, like this picture mentions, on Day 19 the yolk sac begins to enter body cavity. Weird that it went far and gave up.
