I have been reading and looking through the message board trying to learn as much as I can. Before I dive into it, I wanted get a better idea of how to design my run and coop. I want to do things right the first time. First, the coop. I have a storage shed right now, and is the same design as these two, with the double doors: https://www.backyardchickens.com/web/viewblog.php?id=9588 https://www.backyardchickens.com/web/viewblog.php?id=8490-Hot_Wings_Hotel My shed is 12' x 8'. I would like to get some ideas on the best way to convert the shed into a coop. The popdoor needs to come out of the back of the shed. The coop does not need to hold supplies. I have a separate polebarn to hold the pine shavings and everything else. The shed does not have electric. I have a garden hose nearby to wash the coop and water the birds. I also have storm drain I could pipe up to the shed to get rid of waste water. The shed is shaded underneath trees. So getting too hot shouldn't be a problem. Want I am really looking for are good ideas to incorporate in the design that make cleaning and maintenance easier. The run area I am going to take some pictures of to give a better idea of what I have to work with. One of the four sides is going to be the side of my polebarn which will be 36' long. The run is going to be 40' x 17'. I would like the birds to be able come and go in and out of the coop and run as they please. I plan to build a completely caged run. I am wondering what to build the top of the run out of. My concern is the predators. If hawks are my only concern, I could use some type of tree netting. The other predators are raccoons or opossums, or some other critter climbing up nearby trees and trying to climb through the top. Do I need to worry about them, or do they only come through the sides/ground? I do need to worry about them, then I'll use metal chicken wire or something on the top. Thanks in advance for help and suggestions.
