I would keep bator closed till tomorrow, then candle to see if you can see an internal pip. Do you know what that looks like? And then listen for peeping. You need to shine your light into the air cell, even the saddle part and see if you can see the internal pip. If not, I would open a larger size hole in the TOP of the air cell till you can see inside, and see if you can see the chick moving inside the membrane. Make sure while you are doing this you keep the egg wrapped in a warm wet paper towel to keep it moist. If you see movement, keep the egg wrapped in the towel and place back in the bator and WAIT.
