I purchased a pair of BCM's from a breeder here in the valley. I don't know much, but wanted dark brown eggs to add to my rainbow of layers. She said they would be terracotta colored, which although wasn't what I wanted them for, I was fine with because, again, would be a unique color in my egg basket. Wellllll.... the color is regular 'ol brown, very close to the RIR, BR and BO. Any chance this color will change as she matures?
