Quote: I agree with @oldhenlikesdogs considering your goals is a very good idea.
For instance, mine are for eggs and enjoyment - I definitely wanted BO's, then built my list from there. I selected BR and SLW to go with them - they all get along pretty well. Good egg layers and fairly docile breeds. This year I'm getting chicks so have chosen White Plymouth Rocks (good layers/docile), Australorps (good layer/fairly calm/docile) and New Hampshire Reds (good layers/fair personality). The NHR I was hesitant about their personality, but I like the way they look. I also have a mature rooster to handle squabbles and my Rocks rule pretty well, so I think I will be ok with them. If not I will re-home. Space is always a concern, so expanded run space to over 400sq.ft - this should be sufficient for 14 large fowl.
There's no perfect combination - go with what you like the looks of - most of the breeds you are looking at are considered fairly docile.
