Generally speaking, EEs should be clean legged. I know folks lean towards every cross breed is an EE, but that is not the case imo. The original EE fowl brought into America did not have feathers on their legs that I am aware of.
Since there is no standard for EE and the term is used for any cross that lays colored eggs that means they could have feathered legs or not. Most don't seem to but all my bantam EE are crossed with d'uccle at some point since their breeder also kept pure d'uccles so all my bantam EE have feathered legs. What else would you like to call all the blue egg laying mutts if they aren't true EE?
