Anybody mentioned Silver Appleyards? They get big, fairly often go broody and aren't very loud (case by case of course). We had Silver Appleyards when I was a kid and they were VERY mellow birds, only complained when the dog got too close or they wanted out of their pen. But they got big, were very tastey, and they were beautiful. I am not sure about availability though, I know they are a rare breed.
Anyone have an opinion on Saxony's?
