Does Day 1 start the day you place the eggs in the incubator or 24 hours after you put the eggs in the incubator? Thanks in advance Danny
I always count by hours. 24 hours from the time you set them is a full day, end of day one and beginning of day 2. And so forth. 504 hours is a full 21 days.
This is the way I do it and it works well for me: If you put them in before noon, that day counts as Day One. If after noon, the following day counts as Day One.
