Today is day 17 for me. This is my first time incubating eggs. I set 12 and have 6 going strong. I would've only had 2 quitters and 10 going strong but I messed up their humidity. I added too much water, right before I went to bed and forgot to check on them until around 11 the next morning. The humidity had been at 70 all that time. It killed four of my babies. I'm thankful I still have 6 going strong! Air cells are growing and they have nice strong blood vessels. Tomorrow is lockdown!!!
70% humidity will not kill them.
Right! It is more likely to be from shipping stress or temperature.
