I found these eggs today. They are in a coop with 2 bantam RIR hens, and gersey giant pullets and white egg layers, leghorns and Jaerhons. I know for a fact the last BRIR eggs I got were almost white. These look a little bigger then them as well, but are small compaired to my store bought eggs. Could they be from my Jersey Giant pullets? Do they lay a dark egg? OR have the RIR's just suddenly improved their egg color?
