Is Today Day One or Yesterday?

[sunny & the 5 egg layers]

If you set early in the morning, that is day 1. If you set in the afternoon or evening, the next day is day 1. At least that's how I understand it. I set some eggs yesterday afternoon too, so we'll have to have a hatch-a-long!

Hey, can anyone join this hatch along. I actually set my eggs this afternoon so I may be a day behind you guys. I have 2 incubators so when the first round went into lock down in the second incubator, the turner got filled back up with round 2!
