I still am preparing my new coop for when I get my chickens in a few more weeks. I have a small coop (big enough for 4 or 5) with a 10' x 10' fenced run.
I bought some nylon poultry netting on Ebay and was just going to cover the top with that. But then after reading this forum, I decided at least part of it needs tarped so I ordered one of those clear, see-thru tarps. I called the company today to see where my order from 12/10 is and they told me because of the high volume of orders, it will be "about 20 more days".
The run is surrounded with old growth trees so I'm not worried about shade as much as I'm worried about them having a nice dry space. Anything to get them to want to come out of the close quarters of their coop.
