I originally got two Australorps when we lived in an HOA subdivision, because after searching for the 'quietest breed', I was informed these were the quietest. We now live on a small farm, and I no longer have to hide my chickens from the neighbors and HOA hounds, luckily. I'm not sure if the Australorps are indeed the quietest of hens, but they are beautiful, productive and very sweet. They are definitely one of the best brown egg layers, and by far my favorite brown layer. We have had many, many Australorp roosters, and not a single one of them has been aggressive. They are extremely sweet to their girls and to us. They are quite tolerant of our excessive Phoenix summer heat (although I have lost a couple in past years to heat stroke) and produce all summer and winter long. I will always have Australorps on my little hobby farm!
