Besides the chickens using it, how frequent and for what purpose would a person need to get into it, assuming their need to scratch is met elsewhere? I am thinking of a 4x4 foot Purina Coop with an attached 12 foot run extending from it for 4 birds. The egg box and cleanout door would be outside of the run. A 6 foot tall run makes it convenient for me to enter the run but much of that vertical space is wasted on the chickens I've read. And with a roof this tall wouldn't rain blow in from the sides? I was thinking of covering the run with a shed roof that slopes from 4 feet along one long 12 foot side to 3-3.5 feet on the other side. The slope would shield the prevailing wind some and provide greater view of the birds from the backyard. I likely need some type of door or removable panel for crawling access to remove a bird, egg or predator-not. Any thoughts on this approach? Also, rather than a shingled roof, I was considering some type of panel. Any one have experience with corrugated metal or Tufftex either solid color or translucent? I like the idea of translucent for light yet rain cover but is it durable enough? As an option I could get a cattle panel from Tractor supply and bend it in hoophouse shape, cover with hardware cloth and a removable plastic tarp. Any thoughts on this design? Thanks for all your experienced help and advice.
