In Leeds, England, in 1806, villagers believed doomsday had come when a hen began laying eggs with the phrase "Christ is coming" on each one, but it was later found to be a hoax by Mary Bateman, who had written on the eggs using acid and reinserted them into the hen's oviduct.

"History has countless examples of people who have proclaimed that the return of Jesus Christ is imminent, but perhaps there has never been a stranger messenger than a hen in the English town of Leeds in 1806. It seems that a hen began laying eggs on which the phrase "Christ is coming" was written. As news of this miracle spread, many people became convinced that doomsday was at hand — until a curious local actually watched the hen laying one of the prophetic eggs and discovered someone had hatched a hoax."
