We're building our first coop/run, and we need some suggestions. We have a secure coop, and the run will be approximately 12'x40'. Here's the exact scenario: one 40' long wall is our house (which was built in the late 70's and never painted with lead paint, so we don't have to worry about chickens eating lead paint chips). the other 40' long wall of the coop is a 6' tall wooden fence. one 12' long wall is that same 6 foot wooden fence. the other 12' long wall is to be built by us, including a gate, with mesh of some sort. (to visualize this, we basically have a small 'yard' on one side of our house that is perfect for our run. it's already fenced in on 2 sides, and one side is our house.) Here's the question -- we have hawks and raccoons, and would like to keep both out of the run. The coop is secure, so we're not totally concerned about raccoons at night, but all the same, we don't want them wrecking the run roof every night either. Our plan is to connect -something- from our house to the fence. We will likely need to build some framework to prevent sag/add structure. Any ideas on what we should use for the roof? How we should do this? It would need to be something that allows daylight and rain through - not a solid surface by any means. We were looking at a heavy-knotted aviary mesh for this purpose, but aren't sure how it will withstand raccoons and/or neighborhood cats jumping on top of it. Finally, our last criteria is that it doesn't break the bank. Thoughts? Experience? Things we should Avoid At All Costs?
