They started around day 16. I kept the eggs outside in our barn. It was real got and humid that week. Seven more of them hatched this morning. They are leghorn eggs. The chicks seem to be fine and chirpy.
So over the last four days. I have had three eggs hatch. I put them in the incubator only 2 and a half weeks ago. Is it possible for eggs to start incubating in got humid weather ? I can't come up with any other ideas.
