I am on day 20 with a single egg in my homemade bator. It's not moving as much any more(I am not sure, since I know i shouldn't candle it when it's getting ready to hatch!) but it was moving the last time I candled it(on about day 16-17) Temp. is 100-101 degrees F. and hum. is about 65%, which is really good. The egg hasn't piped yet. I thought that maybe last night it would, but it was the same when i woke up. It is expected to be late, since i have had to move the bator+egg due to travel plans(this was done during the first days when it was in the bator and around day 17) Temp. stayed up so I don't think that any harm was done. When do you think it will pip? I'm really worried! I will probably wait til day 27-28 and if nothing happens, I will make a small hole in the air bubble part of the egg to see if and why it died. any advise?
