Day 20 for us. We have 25 eggs in lockdown. Five Barnevelder, 6 Ameraucana, 7 Australorps, and 7 Marans(may be BC, blue or splash). We have no pipping yet but movement in about half of them. It has been a trying hatch with temperature swings, and had the light bulb go out next to the thermostat on day 17. When we discovered it the temp was up to 110 F and humidity was down to 29%. Was probably like this for a little over an hour. So had all but given up hope on anything hatching. But seems like they are resilient. Temp was running on the high side (closer to 100 F) for most of the hatch so was thinking we would get an early hatch. Still waiting for first pip.....
