Okay, so I ordered some fertilized eggs, put them in the incubator and followed the directions to a "t". I locked down at day 18 but have opened the bator to add water and trying not to mess with the eggs. We are now on day 24 with nothing. So, I decide to candle them just to see (I candled them on days 7 and 14 with good results) and what I see is on the big end there is an air sack and the rest of the egg is dark- like there is a chicken inside but I do not see any movement. So my question to all of you veteran hatchers is do I continue or is my clutch dead?
