Just wrapping up my coop construction to the tune of $1,300 in material alone. Keep in mind that I've used half of an already existing 8' x 16' storage shed for the coop part. I'm disabled, so I'm paying for the labor as well. Probably $2K for the coop & a 8' x 8' run when done! Yes, I did everything by the "Backyard Chickens" handbook, but I never dreamed it would cost this much. My 6 Gold Comets will have to live to be 90 to pay for this thing!
