I have 2 batches of eggs. 4 in the incubator and 5 under a broody hen. I've heard chirping sounds from both batches. They are now due any moment, day 20-21. Does it mean they'll hatch very very soon? like in the next day or two? I got SO excited when I heard the sounds, this is the first time I am hatching eggs. LOL. So I'm pretty happy about it.
