I'm on day 18 of an incubation (my first attempt) I started with 47 eggs, threw out 8 after awhile that were unfertile. I could have sworn I saw movement in some of the eggs around 10 days but now all but one egg candle clear for the bottom half, a dark floating mass for about a third and then the air pocket. With 3 days to go I have to believe this batch is a loss. I'm using a Hobavator with an automatic turner and keeping it at 99.5 degrees. Any suggestions?
