John, I love your barn and trellis. It is beautiful We must have been on the same wavelength this summer. I used to free range the chickens in the back yard, but they devastated my gardens and then the hawks discovered them and told all their friends where to find fresh chicken dinners. Well, no more hawk dinners at this house. It was time to put up something more secure and permanent.
I salvaged a bunch of lattice from the side of the road about 9 years ago and it has been dragged around my yard since then, repurposed as temporary chicken runs, garden trellis or whatever. It has held up well in the Florida sun.
I put an "addition" onto the back of my house around a converted raised garden bed that is now a raised coop with 1/2 x 1 inch wire floor. it is open on three sides at the bottom, the poop falls through and the chickens go under for more shade and scratch around. I dig some out once in a while to put into the garden. The brutal sun and heat are my biggest problem here. I put the lattice up around it and used 2 inch chicken wire on the top. Two sides have herbs, various peppers and green beans planted along the sides. As you know, the lattice blocks some of the sun from their run but allows airflow.
The wire would have not been necessary, but I planted just a bit close to the peppers, so the beans wanted to twine into them and I put the wire up to push the beans back. Next time I will plan it better so the wire will not be needed. The green beans growing up the lattice give them some greens and I still got about 3 pounds of beans from that little bit of growth. I thought the beans were played out but where the leaves were picked off by the chickens, new sprouts have formed and they are blooming again. They just might produce through spring when I will plant again, remove the wire and protect the bean plants until they are about 4 feet tall. OH, and clean the lattice. LOL Then the chickies and I will share the bounty.
I am going to do another one at the back of the yard in the spring for my new additions.
