Need some help from experienced hatchers: 1. If I set eggs in the bator on the evening of the 8th, will any eggs on or before the 8th, hatch approx. the 28th? I am second guessing myself. 2. And any eggs set in the days after the 8th will be due to hatch approx. 20 days from that date? Correct? 3. What is the most critical time for hatching eggs? Setting, in the middle, or three days before they are due? Thanks for your help!
