Covered Run?? THANK YOU BYC'ers!

The other night while I was out doing yard work, I heard a loud noise against the chain link of my chicken run. Thinking one of my dogs was being naughty, I turned to yell at him , when I realized a hawk had struck the top of the run trying to get the chickens. Boy am I ever glad I have the top of the run fenced, and didn't have to learn the hard way. And I live in the CITY! I am so thankful for all the advice I learned here on BYC!!!
