OK, many of you asked what kind of incubator I'm using and some other questions. I have a Hova-Bator 1602N Thermal Air. I kept the temp right at 100 degrees except for when we transferred the eggs after taking them out of the turner. It took me about 4 hours to get the temp back up to 100. Why would that be? I transferred as fast as I could. Its now day 23 and still nothing. I candled 4 eggs. According to the pictures, 2 had that bacteria ring, one was clear with a blood spot and one looked like it had a chick in it. It was about 3/4 dark on day 20. Is it safe to candle eggs right now? I'd be tempted to candle them all tonight just to see if there were any good ones but I'm afraid to disturb them.
