Ok, I spent about 2 days going through this forum looking at everybody's coop and run photos , and yours is about the simplest most functional design that I have found. However, the use of the chain link fence sections and all of the sheetmetal on the sides and roof had to have been expensive.
I am using your basic layout as my guide, with treated posts and wire instead of the chain link sections, and I am only going to use metal on my roof. Starting on my coop and run now. Overall dimensions will be 20'x10 feet with the coop at 4'x10'. Should be good for 10 chickens.
I don't know, but I would guess you spent between $1,200-1,500 dollars in yours. I think I can get mine in for around $400. Can't do it in 3 hours, but a good hard weekend or two. I am going to photo document my constuction steps and post.
Thanks for the great plan
