This morning my chicken Penny laid her usual double yolker, but it was white and not brown? She had been laying brown eggs for several weeks now? She is a Hyline, which is a cross between and White Leghorn and a RIR. But they all lay brown eggs. She has been laying double and triple yolkers for several weeks now. I just wonder if the sudden change in color means something is wrong. I do hope she stops laying such incredibly large eggs. It must be hard on her. The triple yolkers are the size of a goose egg. Almost 4 ozs out of a 23 wek old pullet! My poor baby! Do I have anything to worry about?
