This may seem like a silly question but on the 18th day when I remove the egg turner should I wait till about the time I put them in to start incubation or just whenever? Next question. How fast will the internal egg temp drop? I'm afraid to candle. I'm only incubating 12 eggs (white, green, and brown) should I do one and put it back and wait a bit or do them as fast as I can or what's thr best way.
