Here is a typical dozen eggs from my hens. The dark brown eggs are from my Wellsummers, the light blue ones are from my Easter Eggers. The pinkish tan eggs are from the White Plymouth Rocks and Barred Plymouth Rocks and the sort of orangish tan eggs come from the Freedom Rangers. 
But I haven't been able to figure out who lays these tan eggs with the purplish spots. Any ideas folks?
