Hi all! I've never hatched eggs before, and I can't tell if they're alive! We had one chook sitting on 13 eggs in in the banana trees, we figured she'd be okay there because there wasn't any hay and didn't seem like there were any lice in there. But there were. The eggs are so far along that when I candle them, I can only see the air-sac. How do I tell if they're alive or not? I have put them in a make-shift incubator and they are warm enough. I don't have a thermometer or a thing to check the humidity, but I did put a glass of water in there for that. I don't want to do the float test, and I don't want to scratch at the air-sac because I'm afraid of killing the baby. Is there another way besides waiting? Thanks.
