I just candled and I see movement on 11 out of 12 !!! The 12th one didn't look fertile, totally clear and smaller than the others. Not bad for eggs that where shipped, huh? This is my first hatch and I'm using a homemade bator and turner. The way the swing back and forth about 3/4" still freaks me out a little. (I only candle with the large end up and light on top) I'm a newbie, but it seems the air cell may be small, RH is at 50% If they are moving at day 10, what are the chances of them all hatching?
