Help! First time incubating here! We had two eggs start rolling and moving and also chirping, sometimes loudly, on day 18. It is the morning of day 20 and theres NOTHING. No noise, no movement, and still no pip. Yesterday morning, (so the morning of the 19 day) one of the eggs was chirping a little, but not nearly as much as on day 18. Have we lost them? Are they just being quiet because they are about to pip? Is there anything we can do? Temperature and humidity have been kept consistent and never opened the lid of the incubator. How much time normally passes from when they first start chirping to when they pip and begin their process of hatching? Im afraid we've lost them all now. There are 8 total but only 3 have ever had any movement. Any advice would be spectacular!
