I had some shipped eggs with all detached or busted air cells. I decided to set them anyway. I was shipped 14 eggs. I had what at first looked like 10, then 11 develop. As of today on day 12 I have 6 left that didn't stop. In those 6 this morning when I candled I saw big strong movement in 5 of them. The 6th didn't move. The veining looks great. The chicks look strong, but the air cells look horrible. The next week and a half is going to be sooo nerve wracking!
