Hang in there your original plan to raise em up and rehome the ones you cant or dont want to keep is a good one.
The eight foot run is an awesome compromise. I too cannot free range.
Welcome to Back Yard Chickens

from the San Diego High desert. You will find a wealth of info here and the need to develope a thicker skin. Many of us are willing to help and share info. Take what suits you remember the rest for reference. There are some that are passionate about how to do things and others that play it by ear. With such a huge membership you will also come accross some flakes...
Thank goodness you dont have to meet us all in the same room....
My take on all this, and my presonal needs:
Protection from the elements and predators. Easy access for feeding watering and cleaning. Depending on climate in my case extremes of heat and wind that will mean completely open air coop with a roof for shade and some sort of wind break in my case two walls for the prevailing winds.
and First and Foremost have fun.
