Thanks, kstaven.
So how do I go about finding the right birds for me?
Is your primary goal, eggs, meat, both? 
Are the birds ranging over a large area, small area, or penned?
Large flock or small?
Do you need a quieter bird because of where you live?
Do you want a heavy weight standard 10 lb. up or a slightly smaller bird?
Answering these five questions helps cut down the options. Check the breeds database here.
One thing to note is that the egg hybrid birds may lay more eggs per week but will have a much shorter laying span.
Once you narrow it down ask some questions of the breeders in the breeds threads. You may be surprised how much good stock is available here.
Thanks kstaven,
I'm looking for pets that are also egg-layers (flock size of 3-4). My main concerns are personality and the care/space demands of the hens. I would like easy going, friendly, low-maintenance, hardy birds who don't mind being handled and are OK with being cooped up in their house and run on rainy days (basically all winter and much of spring, in western WA where I live). Egg size, color, and production rate isn't a big concern for me. Since I live in the city, noisy birds would probably irritate my neighbors.
My coop is about 4W x 5L x 8H, utilizes the vertical space well, has about 6.5 ft of available roosts, and has two 12in x 12in x 14in nesting boxes. Attached to the coop is a secure 4W x 5L x 5H run with a 4 ft long roost and partial roof for shade/rain coverage. They will have access to the run at all times and be allowed to free-range in my back yard when it's not too wet. The size of the hen door from the coop to the run may be a problem; at 12in x 11in, it may be too small to accommodate the larger breeds.
Thanks for your advice!
