What are the quietest breeds of chickens that you've found? I have a Production Red hen that is exceptionally quiet and hardly ever vocalizes above a contented murmuring. She's also very docile and loves to be picked up and carried. I also have a Plymouth Rock hen who startles easily and scolds loudly every time. I'd like to get a couple more hens so that we'll have enough eggs for my family and I'd like to choose a breed that's on the quieter side so as not to disturb my neighbors as I'm in a suburban area and our houses aren't terribly far apart. Any suggestions?
