What's the matter with Halley's Comet Eggs (better give some pictures)?

Halley's comet egg. Refers to the eggs covered with stars on the eggshell when Halley's comet approaches the earth. 1682, when Comet Halley visited the earth periodically, a hen laid an unusual egg in Marburg, Germany-the shell was covered with stars. 1758, a hen in a village near Heuck, England, laid an egg with a comet pattern clearly painted on the eggshell.

Halley's comet, the star of the comet family, has brought many interesting topics to mankind. Because people don't know its details, they once regarded it as a "demon star" and were uneasy; People can't see its true face clearly, so they try to imagine it. Nowadays, people have uncovered its origin and veil with the help of science, but only one thing is puzzling. That is, in the tropic of cancer around 76 years, when Halley's comet visited the earth, a hen would lay a strange "comet egg".
