Just recently we did a test hatch from a hen that had been away from a rooster for 18 days. The eggs gathered on day 18 and 19 of being away from the rooster both hatched. I knew that they can be fertile for awhile, but that surprised me a bit.I was literally typing just about the same question. If she's been around any other roosters at all within the past 2-3 weeks, whether you've seen them breed or not, then this test isn't really going to prove anything conclusively.![]()
I have also noticed that the eggs from a clean hen are usually not fertile until day 3-4 from being bred by the rooster.
