Not to sound too stupid....but what exactly is the roof on the run supposed to do? Keep out flying predators---hawks and the like? Protect them from the elements somewhat? What about bigger things like coons etc? We live in rural Iowa and the coop is done. We are planning on getting chicks in early spring and will need to build the run as soon as it warms up. I think I'm thinking about this because it is something to think about when you have just been completely snowed in for 48 hours!!! Someone recommended using 30% shade cloth. I looked it up and it looked easy to work with but certainly wouldn't keep a coon out. We are planning on having an automatic door opener which is NOT installed yet......... so they may be out a little in the evenings but will be locked up at night. We were planning on a solid roof but budget concerns are sneakin up on me. Tis the season I guess. With those automatic door openers on a timer---------we had 60 mph winds and would not have wanted the door open the past few days. How do you stop it from opening or shut it once it has? Thanks all!!!!
