So I have a barred rock who has been laying lovely brown eggs since November or so. Today I gathered her egg and it was the same usual color...but with an abundances of purple spots all over. Yes, I said purple! I washed the egg to see if they'd come off, and they got more pronounced and kind of brown. It doesn't seem like the usual change in spots I see in my welsummer's eggs. I realize eggs change shades often...but purple spots??? Should I worry? The picture is of the spotted egg and one of her regular eggs...both shiny because I washed them!
