So I got a green egg from a farm in Long Island. I made an incubator with a styrofoam cooler. I placed a bulb and thermometer inside and water. The temp has been from 98 to 101. I turned it 3 to 4 times a day till day 18. Today is day 21 and nothing so far. I candled it on day 16 and it had a large air sac and the egg was dark. My nerves are shot. Help.
