Sorry to hear they look so bad, but hopefully they will straighten out. I don't know why there would be fluid in the air cells. If you didn't pick them up, are you sure it wasn't just shadow?? ( I'm grasping for any good possibility!). Can I ask why you aren't going to tilt them until day 7? I'm just thinking maybe a little movement might be better than sitting perfectly still all that time. Not a lot of movement, just a little. I know you have researched shipped eggs and I have not, at all. So I'm not questioning your judgment, I'm just wondering what the theory is behind no movement.
Emailed with my sebright contact yesterday. She is collecting eggs for me this week, and I will pick them up next Monday. I should be able to pick up the incubator on Sunday or Monday, but it will be late before I return home Monday evening (almost 3 hour drive, each way... after working all day!), and will need time for the incubator to stabilize, so I will probably set on Tuesday. I'm so excited to hatch again!
