Meaty Coop

I have transformed an old swing set into a coop for my meat chickens. The frame is enclosed by chicken wire, and the whole pen will be within an electric fenced area to keep predators out. The tarp will be placed over the top and the whole side facing the picture. It is almost 8 feet square, and 3 feet high. I have made an opening on the end to allow for easier access to the feeder and waterer that will hang from the top of the coop.
Not sure how I am going to secure the doors yet, but I did use an old garage door track and re bar to make hooks to hang the feeder and waterer from:

Any advice or suggestions would be lovely! Thanks for looking!
