thanks bruce, too small for my pen, it's 9 feet tall in front and the back is 6 ( slanted roof) it takes a lot to wrap it as it is also about 12x 17 feet long . For 10 or 12 chickens
I could go for the larger "sort of clear" pre-made tarp for a run though they are more expensive by the square foot. But they come with tie down grommets so are versatile and can be really tough, I found 20 Mil 'glass clear' (18 oz) at mytarp.com. They also have 30 Mil (SUPER tough) and 7 oz ( I guess ~ 8 Mil??) that is reinforced but not "glass clear".
They also show 20' x 100' 10 Mil clear plastic sheeting for $178 (8 Mil for $145). I can't tell from the picture (it is rolled up) if that is the normal opaque clear or the window glass clear. The really clear stuff I got has a white paper layer (I assume to keep it from getting scratched before it is put up) but the picture of the 20x100 clear looks like a regular roll of opaque clear plastic available most anywhere (though the much lighter weight 6 Mil). I didn't check shipping at mytarp, though I'm tempted to get a 6' x 8' clear for the south and part of the east side of the small front porch (house, not the coop
). The wind whips snow in like you wouldn't believe. I have a plexiglass panel on the north side that works pretty well but the winter wind doesn't always blow from the north
That 9' high section makes it hard to be economical since things tend to be sized in 6' , 8', 10', 12'. Of course, if you are just trying to keep the wind off, there is no need to wrap all the way to the top. They have an 8' x 12' (though "
Size is cut size. Tarp's finished size is up to 3 - 5% smaller.") "string re-enforced" semi clear tarp for $47. The 8x12 20 Mil clear is $63, the 8x12 30 Mil is $110. The 8' 7 oz doesn't come any longer than 12' (though they do customs). To cover the 17 foot sides, you would need the 10 x 20 for $96. Not sure what you do with the extra part at the top and end.
For my coop, I wanted clear visibility for the girls to see out and the people (who, aside from ONE of the 3 cats and me, are also all girls, story of my life
.) to see in. And I wanted as much light passing through as possible since it is a distance from the outside wall, even regular opaque 6 mil plastic cuts a lot of light.
