I am looking to buy some hens. I have been checking out the black and white Barred Rocks, RIR, and EE. I want docile, non broody, easy to confine, quiet chickens. I live in the city and I don't want to disturb my neighbors. I have 2 EE and 1 RIR. The EE are more verbal than my RIR. I am not sure if this personality or breed. What can someone who has barred rocks tell me about the traits I mentioned above?
