Today is day 14 for my shipped eggs. I have 6 definite yes, 5 maybe and 2 that didn't make it. The 5 maybes have wobbly air cells but seem to have veining and movement. The 2 that didn't make it quit at around days 7 and 10 I am guessing. When I candled them the one that quit at day 7 looked like a blob the size of your fingernail stuck in one spot right under the shell with no veining. It had teeny wings and feet, no beak and 2 huge eyes. The one that quit at around day 10 had air cell problems. I carefully opened it from the top of the shell and saw that the air cell was peeled away at opposite sides of the shell. As I looked further I saw the little chick encased in its amnion--no heart beating or signs of life. Its body was very soft and pliable. The beak was formed, it had huge eyes with the lids just beginning to form, little wings and feet, tiny little marks where the feathers would start from. It was amazing.
Now I have to sit tight and hope for the best for the 11 remaining!!
