I just wanted to throw out there that with the exception of two breeds, all of my chickens are different breeds and colors. I have two golden laced Polish and two golden lace wyandottes. Other than that, the rest of my 13 are all different breeds and colors. I have never had/seen a problem with them picking on each other. They all shipped to me at the same time from www.mypetchicken.com . They grew up together, etc.
