there is a breed or three for more or less any circumstance. The trick is to find a breed that suits the conditions you have - think along the lines of the gardening motto 'right plant right place'.
Whether you're going to let them free range or pen them is an important criterion; some birds can't handle confinement, while others are not at all predator aware, or are poor foragers. Some people want their birds to be pets, so need a placid type, while others want their birds to largely fend for themselves, so something more lively is best suited there. Some want lots of eggs, others care more about appearance - there are just loads of possibilities. If you make a list of what you are looking for, you can then search for a breed that fits. There are some good comparison sites to help, e.g. http://www.sagehenfarmlodi.com/chooks/chooks.html (aka Henderson's handy dandy chicken chart).
Did lots of research for the plymouth rocks (as their supposed to be super friendly, curious and docile, dual-purpose and good egg layers and very hardy (as it's cold in the uk and they're going to free range in the garden)). But the site will definitely help as I grow my flock 
very exciting!
