Hopefully I do this right. I attached a couple pictures (sorry they are sideways!) of an old greenhouse located on the property. I tore off the greenhouse material which left me with the frame. You can see it has upper and lower "benches". What should I do with this frame? How can I predator proof? Should I frame in large windows for ventilation? Should I leave the "benches" in or take them out? There is a water faucet plumbed inside, how can I use it? I am new to chickens. We have lots of predators of every kind and I don't want to lose any of my new babies! They are 4-5 weeks old now and ready to be outside, so i need to get this coop finished. I will also build an enclosed run, but getting the coop done is priority. Thanks for any help!
