Good thinking. When I thought something like that was happening to mine.. it was always cracked and repaired or body checked.. Pushing it all the way through the system verses making something pop out that was already close by *seems* less likely to be caused by a spook..It’s possible there was just a “disruption” and something happened what disturbed the egg cycle, like a predator walking around the coop at night, or a storm.
But some animals have been known to evacuate as they escape.. though that's not what was described... I like to play investigator, when it's helpful..
The following article has lots of useful information.. noting almost anything is stated as possible cause being virus or disease.. but please don't jump to that conclusion, without good reason..
