Hi!! One year chicken Momma... one of my four Orpingtons has laid 2 very small eggs. One last week and another today. She seems normal in every other ways. Is this something to be concerned about? She is the smallest of the four hens...always has been somewhat little compared to her big sisters. They all get along and free range all day and locked in a coop at nite. Yesterday all four eggs looked about the same???
