I've never had experience with any of those, but from what people tell me - Faverolles are VERY friendly and easy going. I love them and their adorably beautiful presence, so I'd say go with them. Although Langshans are pretty rare, so I'd also point to them. Of course, this leaves Sussex out, and, I really don't know what to say on those anyway besides that one of my "Brahmas" is a Sussex cross, and the only "Brahma" that is really flghty and not too friendly. (note to people looking for McMurray Brahmas. . . Not all of them are purebred.
