has anyone or does anyone use this for covering thier runs my girls are in a 33 ft by 33 ft run or mite be just slighty bigger and the run has netting all the way over it but i would like to get it covered so it can stay dry and give the girls some protection , http://www.ideas-4-pets.com/lucky-all-weather-chicken-run-cover-777-p-4184.html. it does seem pricy and they dont really do sheets big enough for my run but if i got this then i would in time half my run and then just split the girls into groups of 10 { have 20 birds } but would llike to know if its any good
