So I made a homemade incubator that is working fine and I'm monitoring humidity and temp on 2 different gadgets. I originally bought 4 eggs but now only 2 are developing as I discarded the bad ones that started leaking. This is the Eighth Day these two eggs are developing and they're moving around and seem to be developing fine, but when I candle them one of the eggs seems to be developing on the side of the egg and on the other side is just an empty space but on the bottom there seems to be an intact air sac that is not connected to the other empty space if that makes sense I'll try to post a picture. In the other egg the air sac is kind of drooped down but not a lot and it's not moving so I'm not that concerned about it but what I'm concerned about is when I candled on both sides it's what looks to be two air sacks on both sides that both are intact so I'm confused on what that means since both of the eggs have empty space in them but they seem to be developing okay. They are in a carton right now upside down and I am tilting them from side to side and also rotating them. The temperature that I have ranges from 100 degrees Fahrenheit to 102. But my humidity ranges from 40 percent to 58%.
