After waiting somewhat over the 30 days I'd estimated they'd need for hatching, and finding that only one had been fertile (and that one didn't completely hatch), I removed all the eggs my girls had been setting about 2 weeks ago. Since then, I've seen the males attempting to breed again (even this late in the season), and today I found 3 eggs in the barn! Why are they restarting the process? I thought once they'd laid for the season, they would stop. I remove the 3 eggs, but am debating whether I should try to incubate them or not. Any chance any of these might be fertile so late in the year?
