If you humidity is high the one concern would be if the air cell is getting big enough. Just keep and eye on that. You can find drawings of what that would look like when candling. As I understand too humid can make is so the air cell is not getting big enough. Someone here should correct me if I am not saying it correctly. LOL. I have two eggs we are waiting on now. The others do not seem to be doing anything. If we accomplish to get 8 to hatch we would have 60%. I was hoping for a minimum of 9. Time will tell.
