Yesterday about 7am. I think scheduled hatch date is 7/13. I'm also testing the HatchKeeper App to keep track of the dates. We'll see what happens... I'm only incubating NN mix eggs right now. Maybe at candling I will add some Barred Holland to replace any bad eggs, I don't know yet if I want a potential staggered hatch in one incubator since this is my first attempt at incubating.
I could put the ones on lockdown in my home made incubator if needed.
According to my calculation's on when you put them in, you should start your lock-down on July 10th for a July 12th hatch.
