3 chickens, BR, Americana and PR in 3.5x5 house with 12x12 run. We have no shade. This summer I used shade cloth. It seems OK, but does not give the cool shade found under a bush a big tree. I have been researching vines, looking for a vine that is deciduous so we will have winter sun and not too woody so it won't tear up the 1/2" hardware cloth run. Researched poisonous and found varying answers on lists. Has anyone used coral vine? Can Pampas grass cut a chicken? It would have such nice drooping shade. I would really appreciate Any suggestions. Thanks to all you folks out there.
