I might be wrong but just becasue they don't have exact matching markings doesn't mean they aren't that breed right. I mean I'm white but I didn't look like everyone else when I was born. Everyone if different and as far as I'm concerned so all animals, including chickens. I can promise you one thing for certain. The feed/farm/grain stores don't know anything about chickens.(well most of them) They pry labeled them wrong. I think it's one of the three things I mentioned. I am wondering tho(I may have missed it) What do their combs look like. That might be another thing to go off of.... I'm so curious to know. I want to see more pics!
