Nice start
If I may ask, how many egg birds are you planning on keeping? (Again, I apologize for always peppering you with questions - hmmm.. is that what the '?' icon is for?)
For our birds, we will be using a pre-existing cinder block building that looks like an old-fashioned vegetable stand. It's exactly half the size as your coop (10x12) but it will do
, It has a large opening on one end which is 6-8' wide by 4-5' tall that a previous owner covered with a screened panel. There is still remnants of a counter top that bridges to the outdoors. It looks like there may have been a roll down that slid down over this window at one time but it is long gone. I figure that, with a little modification, this will make a great entrance/exit area for the birds. On the perpendicular wall, there is a walk-in door. Since the door needs replacing anyway, I'm considering a double door - a screen door over a solid door - so that we can get some cross ventilation when needed. I really would have thought vege stand but we are in the middle of nowhere and the road isn't even nearby. Maybe someone here knows what it could have been used for previously?
Nice runs! Will you be using hot net for fencing?
