Okay, so I am going to be building a new coop (actually re-purposing a shed I already have) The old coop was small as was the run. I was letting the gals free range alot but unfortunately I lost 2 of them to foxes inside of a week. So the wife has instructed me that the new run is to be LARGE as they will no longer be roaming free about the property. The new run area is going to be huge (think 40' x 40' and you'll be getting close). Because of the shear size of the run as well as the fact that it will be odd in shape, the question is, can I go without a cover? It is nicely wooded giving lots of protection from hawks and I plan on about a 5' fence. Thoughts?
