I find regardless of what day you lock down, the chick will hatch on day 21. Mama hen is still moving eggs around when they hatch on day 21. I've had them hatch while I'm still turning them..to my surprise! The earliest being on day 18. Really surprised me. Have had several hatch on day 19, the day after I stopped turning. Guess they hatch when they are ready.
Whoops, I have some EE, and OE eggs in that go into lock down on Wed. I can't see in them either. If you are seeing a nice air sac, they are probably doing just fine. All we can do now is cross our fingers.
