My daughter and I acquired 4 Indian Runner eggs 30 days ago. This is our first experience with this. . I'm pretty handy so I made them a nice incubator and the conditions were good and I followed the protocol well except for the humidity being too high for quite a while before I realized it was wrong. We candled weekly and saw amazing movement. Changed things up to lockdown conditions on day 26 ( Friday) and haven't had anything happen since! and I can't see any movement when I candle them now. Nothing in the air sac either. Today was day 30. We're growing unhopeful and sad. What's wrong??
