Chicken Math is not a factor.  City ordinances limit me to 8, maximum.  Well, I'm limited to 4 dogs/cats/poultry per address, and it's a double with 2 addresses, and I'm going to assume it's 4 EACH not 4 TOTAL. 
		
		
	
	
   I already have 2 cats and 2 dogs, and my tenants have 2 cats, so TECHNICALLY I'm only allowed 2 chickens.  I'm compromising at 5.  
Sooooo... this would be the open coop/run area.  No additional runs.  No enclosed coop.  Just a super-secure aviary.  
Mostly I'm trying to maximize my yard.  It's only about 30' deep from the house.  
My house is the big white one in the middle-ish.  You can see the fence that used to divide the yard under the staircases.  The yard is long and skinny, and crosses behind the blue-house neighbor's lot.  That extra width is where my garden is (was hoping for current aerial showing the garden... Google disappoints; tho I do like the angle of this photo).  
If I put a proper coop/run in the yard, I'd be giving up a LOT of space.
Paint is on the "to do" list....   it's a really long list right now.
