Well, I had no restraint. I set a 3rd batch in the incubator. Put in 41 eggs. Lockdown was June 17th at 7:20 pm. Eggs started hatching early afternoon today. 2 have hatched so far, and one more is fully zipped. What causes such an early hatch? They weren't due until the 20th. My temps were at 101, the whole time, and humidity was in the high 20's. The eggs are zipping quite fast. They are wanting out in a hurry. !!!!!!
