Thanks for doing such a thorough job of addressing strange egg issues. Most of us would have no clue what was going on. NOW, having said that, my egg shape issue isn't listed. I only have two hens in a large coop with a pretty clean dirt floor that gets dug up by me frequently. One of the hens lays eggs that have little granular bits on one end that are covered by the shell material. The egg interiors are normal, rich and very tasty. What is causing the little itty bitty brown granules on the egg end? They get fresh water and excellent nutrition. Thanks!
