I have been thinking about a shelter for my birds during inclement weather for some time now. My criteria are that it had to be moveable,easy to build and hopefully inexpensive. So,last week(last week of November 2013)I was dismantling an old portable shelter or garage.It measured 12'x20'. As I was pulling off the old torn and rotten plastic an idea began to form. 12'x20' seemed a little large.Maybe 12'x16' would be a better size. What if I cut the bottom off the supports,leaving about 18" plus the rafters? What if I attached this structure to a couple of 2x4's,pressure treated and reinstalled the bottom rail of the garage at the bottom of the new structure? This would give me something to attach it to. Still a little wobbly?I used some 10 gauge galvanized wire and small turnbuckles top to bottom and bottom to top on each side. It seems to be nice and sturdy. I bought a fairly heavy tarp,12'x16' and 50 ball bungees.I kept the west side down to the ground to protect from the west wind which is the predominant direction here and also the snow and afternoon sun. I found that I had not squared the structure properly when I went to attach the tarp.This meant having to loosen and tighten turnbuckles until the tarp fit.Because tarps are about 6" smaller in both directions than advertised,I might use a 12'x18,next time although it is just fine the way it is built. A test came 2 days later in the form of a 8" snowfall and 40mph winds.Everything held up fine. The girls are getting used to it and I'm a hppy camper.Total cost,about $65.00. Since we are talking about chickens,here is a chicken picture of my 24 week old Ameraucana and her best friend a silver laced wyandotte.They are inseparable. .
