It seems like several folks here have used the clear corrugated roofing on their coops and/or runs. I've found the manufacturer of this stuff -- Suntuf -- on the Web, but am at a loss to figure out how to get the stuff in Chicago. Did you order it through your local lumber yard? Let us know! I'm trying to get quotes on building a more permanent run for my chickens (3 grown hens and 4 1-week old chicks) and would love to use the Suntuf to roof the run. I just need to figure out how/where to get the stuff. Thanks!
