Back when I was still having to spend most of each year in Denver, here just a few months each winter, I scored BIG time one winter during the annual S.W.E.E.P. event when people sit on the curb all the crap in their yards and homes too big to set out for usual garbage pickup. Being a dumpster-diving packrat I of course SCOUR the neighborhood for treasures (though I AM better now about putting stuff OUT for pickup as I try to make my yard look less 'Third World" each year). Two households had set out a LOT of chainlink driveway gates....I did not know WHY I wanted them, but I am John Starnes....it was my JOB to make a few trips in my van and stash them in my backyard before making once again, reluctantly, that LONG drive back to icy brown Denver in April.
Once back the next fall, one early evening I was getting "altered" on a certain herb, free-associating as usual ( I LOVE how cannabis can enhance creative thought processes) and starting playing around with mix-and-match combinations of these gates. I soon realized I had JUST the right mix to make a very sturdy and spacious henhouse. I constructed it atop 4 layers of scavenged carpet to keep racoons from digging their way in from the sides, and used various scavenged wires and cords to lash them all together into a very rigid structure not even jiggled by hurricanes to date. At sundown the chickens go in, I take "Mr. Rooster" out and put him in a dog carrier in the garden shed, cover that with heavy cloth then close the shed door (this spares my neighbors his crowing as I let him out 10:30 AM on weekdays, 11 AM on weekends), then close the henhouse door and tie it shut with a piece of phone cord to keep racoons from forcing it open.
It cost me nothing except some physical and mental energy, and for four years it has also served as an arbor for "Gracie's Grape" and "Gray Street Grape" for shade in summer, sun in winter for the hens, and grapes for me.
