Tomorrow is day 18 for my chicken eggs. I decided to candle tonight so I could do it with the room good and dark. Some of the eggs are looking right where they should and others look to be only halfway? This whole hatch has been disappointing. I set 42 eggs. Ended up 6 were clear. I'm down to 13 eggs as the rest have quit at various stages. The ones looking halfway have good veins and I saw movement in some of them too.
