I am looking to add to my current pair of chickens but want to be sure to get calm, quiet birds that are reasonable egg layers. I currently have a sweetheart of an Easter Egger and a trouble-maker Lakenvelder. In your experience, what breeds make the best city birds? I have heard Orpingtons and Barred Rocks are pretty quiet and gentle. They are also pretty heavy and I live in a hot climate with mild winters.
