I looked back and I found a photo of the egg on Day 4, which was on March 24th. So I set the eggs on the evening of March 20th. That means today is Day 20 and tomorrow is Day 21. No pips yet.
I am concerned at this point because I have to keep opening the incubator twice a day to re-wet the sponges. If I don't do this, the humidity drops too low, even with both water chambers completely full. After this hatch I am going to do some serious experimenting with it because for the amount of money I payed I shouldn't have to deal with sponges and opening it during lockdown! This evening, I did a quick candle. I didn't take the egg out or anything, I just lifted the lid slightly when I was grabbing sponges and put the candler in front of the air sac. Since I first posted, the air sac has grown drastically and is lopsided. It extends much further to the right than the left.The rest of the area above the sac is dark, but it looks like the area between the air sac and the chick is lighter in color. I am not sure what this is, the yolk maybe? It also appears the chick may have shrunk? I may be mistaken but I think I remember the dark blob extending further down, basically to the point of the Day 18 air sac. I didn't have time to keep looking, but it brought me here! I really don't want this little guy to quit on me... any thoughts???????? How do you tell when an egg has quit??
